David Jones hasn't got the time/inclination/something or other.  I
asked him some while back, and he said he was quite happy for the file
to be zapped from the archives.  I had forgotten to do that, and have
just moved it to obsolete/help

The reason the texlive key is there is that the file is also used (as
a BibTeX file, no less!) in preparing the TeX Live documentation.  The
key doesn't appear in the other derived format, CTAN
help/Catalogue/ctfull.html

It depends how you interpret the phrase.  I would claim that it's
pretty readily interpreted as `take this if you want it, but it's not
part of a standard distribution'.

Give an opinion if you want to classify, don't if you don't.  Don't
try to classify without giving any opinion: that way lies madness...

No-one's talked about billions of users yet, have they?  There are
only 100 million PCs (or something) in the world!

This is precisely what Graham's stuff gives us.  We're very lucky that
he was willing to take up the baton when David Jones had to give it
up.

As I said, the texlive key performs an entirely different function.  I
didn't read this discussion as claiming that these cataloguers were
going to construct test suites, or anything of the sort.  I'm happy
that the cataloguers `merely' collect opinions and distill them into a
digestible form, as Graham Williams has already started to do.

In my view, a project to construct a test suite for every package on
CTAN is doomed to failure.  (For some reason, my fingers kept wanting
to type `dodo' where I meant `doomed' ;-)
