FWIW, GnuPG used MD5 only for PGP2 compatibility.  From rfc-4880:

   Implementations MUST implement SHA-1.  Implementations MAY implement
   other algorithms.  MD5 is deprecated.

SHA-1 is is an important part of OpenPGP and used in ways which are
resistant against collision attacks.  Thus it is not easy to fade it
out.  A paragraph explaining why certain algorithms re used by default
does make sense; though.

Yes, that is important for real world security.
