As I did those updates..
well explained, thx.
But this then seems to be a more general problem of how we want to
support a switch an application from one ESR/LTS release if it is EOL to
the next.
not terribly differently than others -- with an abundance of end-user education and
caution?
tbird version update -- across ESLs or not -- breaking one's install, or eating
one's mailstore, is not _automatically_ a universal fact
for tbird, it's more often an issue specific to one's system; not uncommmonly,
your config &/or your addons.
for other ppl, the upgrade's been working fine in production for awhile now with
upstream releases, with early fedora tbird builds, and now the fedora release pkgs.
for me, the lack of a long-overdue v102 update was 'costing' much more than not

ESL or not, how exactly was thunderbird 102 'pushed' to ppl's systems?
did they
enable autoupdates?
or,
click to allow the update?
if tbird's a critical update for 'you', you
do have backups of your tbird configs & mailstores?
keep up to date with thunderbird version progress/news/chengelogs/notes?
remembered that addons are not tbird or fedora issues, and checked current/future
compatibility of your addons, as well as whether they're well maintained?
communicated issues/bugs/etc to the respective projects?
and
have waited to update until after checking/verifying that it works for you?
and, in case none of that was done, since firefox/tbird major-version update issues _are_
historically well-known (if unfortunate), you froze version upgrades of tbird on your
system

to make sure that you're never surprised by an update you don't want/expect?
