If I understand you correctly, users don't expect this historically. So,
do you think this warrants a comment in the release notes? We already
have a section about "prepare for downtime" [1], but if this went more
smoothly in the past, it may me still smart. Something like:

"""
In contrast to normal upgrades of sendmail, during the upgrade of buster
to bullseye sendmail will be stopped, causing more downtime to the
service than other sendmail upgrades. Please read [1] for generic advice
on reducing downtime.
