look like a bug/feature in a OpenCycleMap style.
as you said, in a lot of country bicycle=yes is already
the default value for highway=path
highway=path" + "bicycle=yes is not better than highway=path
but to use each country's default values on a global rendering,
you probably need a preprocessor which OpenCycleMap maybe don't want.

look like wrong. some mtb tag exist (including the misued mtb=*,
misused because I doubt there are so many signs saying that
a path is forbidden to mtb's.
https://taginfo.openstreetmap.org/search?q=mtb
what's a path not MTB suitable ?

it would be a good suggestion to suggest to iD to improve the interface 
in order to ask users to fill in the real access restrictions.
I had seen a path between the street and a shopping mall with horse=no 
because iD had asked the user if it was allowed, and he considered
that it should not be ridden :) while there was obviously no access 
restriction, only the feeling because the editor ask it.

add mtb: related tag.

it seem a good idea.

after the general discussion here, it is up to the Italian community
to decide. This can be done at the same time as adding the mtb 
information or someone can offer a mass edition in Italy
if the local Italian community wishes so.
