FTR: This has an obvious sideeffect though: If (lets say) foo/sid has
feature x and advertises it in the long description (but short didn't
change), while foo/stable didn't have it, it is undefined which
description will be shown, it could be any – but it will be only one,
the other is 'discarded' as duplicate.

Never happens with stable/single archives of course which I was thinking
of, but in sid you would see it relatively often. Multiply this with
'outdated' translations still being shown as current. (Did I mention
that I dislike feature lists in descriptions as they are always out of
date even without that?)

You could mix and match it of course, like dropping it for stable as
long descriptions aren't going to change there, so that short would be
identifier enough, but well…

P.S.: version number doesn't work here nicely, as experimental/security
do not have translated descriptions, but can piggyback on them this way.
Which is the historical reason for this alltogether, as they were first
not in the archive and then just file imports (which they still might or
might not be, I have no idea – and my last speculation in a train ended
in the previous mail - I blame the broken air condition…)
