I think it's a good idea. All those problems with wrong article counts
due to "holes" in the article numbers have driven me nuts while doing
nnmairix...

However, saying that adding this feature to all back ends is "no
problem" seems a bit optimistic to me. Gnus has lots of back ends (close
to 30), and there are external back ends like nnshimbun which are not
part of Gnus. So in my opinion the old code should be kept and used as a
fall-back method for back ends which do not store the unread sequence in
the info list.
