In other words, taking minetest-uri as is currently doesn't seem too
good of an idea. Does the plain git/vcs updater work for those
packages then? I assume at least some of the packages should be tagged
properly in git, are they not?

Sounds good to me.

Fair enough, if that requirement is actually enforced by ContentDB,
that's good. It does make the AUTHOR/NAME URI syntax look a bit weird
tho.

Well, that's one way of resolving this issue, another would have been
to move the comment to where it makes sense.
All in all, I think I'm rather content with this patch now, but I have
a final nitpick w.r.t the updater. "upstream-name" is a weird name for
a property that will supposedly be used by only one updater (and even
if different updaters were to use it, would not each one have slightly
different, but perhaps sometimes overlapping expectations for that
field?) I think a better solution would be to set home-page to the
ContentDB page, assuming that is acceptable. If not, perhaps having a
"refresh-url" that is well defined over all refreshers and supersedes
home-page if specified might be a more appropriate solution.
WDYT?
