It is what it is designed to do.

Yes, but you have to do it outside of Mailman. E.g., set up a cron to
run on say the 3rd day of the month that runs a script that removes
the .txt files for the prior month. There is a small risk to this for
the same reason you can't remove the current month's .txt file. If a
post arrives for a month whose .txt file is missing, it will create a
new .txt file containing only that post, and that file will be gzipped
on the next nightly gzip (or immediately if GZIP_ARCHIVE_TXT_FILES =
Yes in mm_cfg.py), thus losing the prior contents of the .gz file. Of
course, everything is still in the list.mbox/list.mbox file, so it
isn't completely lost, but it's awkward.

No. If there is no .txt.gz file, the archive link will be to the .txt
file. The only reason to have the .txt.gz files is to reduce the size
of the file(s) a user may download, but with many web servers
configured to expand .gz files before serving them, this is not a

Of course, the .gz files do save space on the server, but only if the
.txt files are removed which isn't too practical as I note above.
