Pterodactly gripe / oGnus wish

[sperber@informatik.uni-tuebingen.de (Michael Sperber [Mr. Preprocessor])]

I love my Pterodactyl.  Good riddance to tm!

But, at the risk of repeating something which has been said an
innumerable number of times already:

The numbering problem is the single most annoying aspect of Gnus.

I look at the *Groups* buffer.  It displays the correct number of
(ticked) articles in a group.  I enter the group and it prompts me
with a totally bogus number of articles to fetch.  Why can't Gnus
count at least as well as I can?

As the gaps between retained articles get larger, Gnus slows down
from a barely tolerable level to a quite intolerable one, even if
the total number of articles is quite slow.  Why?  I can't think of a
good reason algorithmically.

The fix described in the FAQ is a major kludge.  Why do people have
to be aware of the article numbers used internally by Gnus?  If the
FAQ answer has any sort of official status, why isn't there a
GNUS-GROUP-CLEANUP function bound to a convenient key that does the
job?

Fixing this should be a priority for oGnus at the latest.
