  I had a thought last night in that there does, in fact, exist a way to
include the information without changing the syntax of the protocol.  The
MIME type that is returned can have parameters, and these parameters can act
as small headers, so:

20 text/plain; charset=iso-8859-1; size=1345
20 text/gemini; size=2003; modified=2019-08-18T17:15-05:00
