Package removals and PROP_RM

[Barry deFreese <bdefreese@debian.org>]

Folks,

I've been working on removals and QA uploads and such but I feel like 
I'm working in a bit of a vacuum.  Do we have any establish guidelines 
for removing a package vs PROP_RM?

A couple of examples:

mesa-legacy: Orphaned, buggy, I can't even find an upstream.  However 
libgl1-mesa-glide3 is an optional depends for tlprender.
gqmpeg:  Orphaned, buggy, hasn't seen an upload since 2004.  Upstream 
inactive since 2004.  But has moderate popcon score.

So my thought process is PROP_RM mesa-legacy and ask the tulip 
maintainer to remove the dependency and then RM: it if someone doesn't 
pick it up in the mean time.  For gqmpeg, I'm tempted to just RM: it?

Any guidance here would be greatly appreciated.

Thank you,
