If you want to know those kinds of things then you should not be reading
the manual pages for a given implementation, but rather standards
documents, programming guides, or the like.

Manual pages (should) document the implementation.  If there's a problem
in the implementation that can/should be fixed, but for some reason
won't be fixed right away then it should be documented in the BUGS
secition of the relevant manual page(s).
