incomplete isn't the issue - it's woefully out of data that's the
problems. mirrors in fail-over only work if they are identical.

and the heuristic was fairly questionable iirc.

I disagree - people have a hard enough time with key=value.

I don't think that file is human editable at all.

bye current method you mean 'for apt'

this is just a good reason why apt's configuration is a mess, not why
this has to be done on the repo-side.

the trick is combining the information density with sensible defaults.

This is why the gnome people have taken a lot of time trying to get
config options more sane - it is not a trivial undertaking.
