They were marked obsolete because the problems that they fix don't occur any
more on the platform that are reasonable porting targets now. In other words,
the doc/posix-functions/$FUNC.texi file does not list a problem.

Why? It's not an incompatible change when a module becomes obsolete. You can
continue to use it.

The "more information" is the documentation. For example, for 'memchr':

  Gnulib module: memchr

  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some older platforms.
  @end itemize

What extra information would you find useful here?
