Not always. In some countries access law, traffic and enforcement matches.

In some you may have situation closer to 

(1) law says "bicycles are illegal to drive"
(2) law is ignored by everyone

In such cases bicycle router showing "it is illegal to drive bicycle here anywhere"
would be useless, and people would want one matching reality. 

The question is whatever such de facto status
- can be recorded in OSM
- should it be recorder (ab)using standard access tags
- if recording it is OK but access/bicycle/etc should be kept for legal
  status then we need new tags (bicycle:de_facto, bicycle:de_iure ?)

? sometimes intention is unclear ("I hate anyone driving here"
is likely untrue), but signs are clear

No only signs - there are also gates or physically blocked access
in some other way. Or permanently placed police/guards.
