Yes, I agree that it would be very useful to tag whether a ref (or name) 
is signed on the ground or not.

I have tagged a few refs for C or U roads from diversion signs, but they 
are not (usually) signposted as such. Also there's a lot of streetnames 
which may not be signed, but are known from local knowledge or OS 
OpenData etc.

There is a proposed unsigned=yes tag on 
http://wiki.openstreetmap.org/wiki/Proposed_features/Noname
But that is not very helpful, as it doesn't specify whether it is the 
ref or the name (or something else) that is unsigned. Something like 
unsigned:name=yes or unsigned:ref=yes would be better.
And it could be used for other language names or alt_name, eg 
unsigned:name:gd=yes etc.
