Yes, we looked at several popular sites and the voting UI, and picked one
of the existing variants.

No need to do batch-updates.
$ rpmdev-vercmp 1-1.fc32.copr1234 1-1.fc32
1-1.fc32.copr1234 > 1-1.fc32
But note I proposed to use %buildtag after %dist, not vice versa. Moving
%buildtag before %dist would mean that we loose the benefit of dist
tag -- when both fcNN and fcNN-1 builds exist in multiple repositories
(notable example is 'fedora' and 'updates') fcNN is the preferred variant
for installation.

No problems to admit a change of mind ;-) that happens all the time.
Mainly I was afraid that source background builds will eat too much of the
frontend storage. But there don't seem to be that huge performance
problems, and that worry was probably a bit over-pessimistic.
Also, source builds are not yet visible in statistics, so if there's any
problem with source builds - it isn't anyhow obvious (Dominik is working
on the fix in issue 295).
