no, it was not "forgotten" - the absolute last thing we need is
"automatically introduced problems", particularly if - especially as -
the setup is using debian/testing.
debian/stable and "production" servers with carefully pre-planned
setups, or "toys" where nobody else is relying on it, or "your own

yes please don't do that without consulting everyone, first.
to give you some idea: the notification schedule that servers used to

updates, and one year for a reboot.

which is precisely why you don't "upgrade" a server, especially
without notice or discussion. we are now critically dependent on that
machine having 100% uninterrupted power.
if there is a power-outage in the data centre that causes an
unscheduled reboot, resulting in that machine going down, and we are
critically reliant on it for testing at the time, someone has to drop
everything they're doing, scramble to look up the procedure for
logging in to the virtual console, and then work out how to recover
