I have told Kendzi now it is not working (with version 11425 it does) , but
as you can see in imgur  I have done some capture I can assure it works
with more than 9000 traffic signs kinds from 32 countries.

When I had discover Roadsign plug-in I wanted a complete scheme for my
favourite subject. At first approach in 2013  I know traffic signs need
somewhat to "localize exactly" and the option in Roadsign plug-in was a key
direction= ) .In parallel I have continued with a Style for JOSM. Also I
have found a way to show in "3D" in a plug-in of JOSM called Kendzi3D and
develope the possibility to show this traffic signs with the orientation
with direction= key.
But later, as Roadsign updated were so difficult and I have not control of
it, when I have finished all three legs, I have checked the wiki and
discovered Finnish approach  and Deutsch aproach  and decided to
start a preset for JOSM, and in the preset and with comments for some user
JOSM did not control direction tag I have changed all the scheme of the
preset to traffic_sign:forward/backward . I have started with my
country: Spain. Last big changes version was in 2016. And one day I saw
someone localized to French some strings. I had checked Taginfo and
Overpass and watch some Spanish traffic signs were around the world (I saw
Spanish traffic signs...in Texas USA ) .So I have started to investigate
other countries. I have took information of other countries as Finland or
Belgium and start with Belgium because they have less traffic signs than
other european countries. But I was so late.
Preset was so huge and also I a bad programmer than it started to make many
problems to JOSM, and in a issue they say me "split the preset"  . Now
you have 32 preset from 9000 different traffic signs with forward and

I think it is a good opportunity to give traffic signs the importance they
have. The scheme of :forward/backward, the two-letter country code allows
to add any traffic sign of any country.

Thanks to Spanish preset I saw the necessity of make also a destination
tagging scheme, because multiple values does not work well with traffic
signs, also recognition systems from people like Mapillary or OSC use to
identify any traffic sign individually. Proposal is done , waiting for
people to watch it and make it yours and better, modify it , ammend it, cut
it, crop it,erase it... Precisely I am not the best programmer in the World
(I'm only a kindergarden teacher) . Make useful all this stuff. Make your
own stuff about that. It is only an idea.

I think use subkeys (traffic_sign:forward/backward is better than using
other key as traffic_sign:direction=forward
First option give you the country and the code in one pair of key=value
Also opens the opportunity to use traffic_sign with no subkeys to mark the
kind of traffic sign it is (warning,
complementary,regulatory,compulsory...) as a future scheme to unified
traffic sign international system like Mapillary's 
Next moths, next years you will hear about Mapillary, about OSC, about
recognition traffic signs system, about open data agreements with some
goverments (if Spanish government does, other regional governments can do
the same...and other countries goverments also).There are people get ready
to have the information and to give it to us OSM mappers (with plug-ins, iD
custom editors, iD custom layers.
Now traffic signs presets, styles, taginfo (there was a mistake with it
adding 3 more countries and 1000+ traffic signs codes and today is not
working but It will be online soon.) , Kendzi3D (I know with later version
is not working...all Kendzi3D plug-in with JOSM, there is an issue opened
in JOSM's trac and Kendzi's Github), some ways in OSM Lane visualizer 
... for 32 countries with 9000+ kinds of traffic signs...but in the future
it can be +26000 from 67 countries (thanks Wikimedia projects), covering
more populated countries in the world.
Are we ready for traffic signs?
I hope so
