The complete lack of bug reports and maintainer interaction usually
suggests low to no use and heavy bitrot. If that is not the case
here that's fine, just asking..

FYI, feature-wise the in-tree DRBD is frozen. Maintenance only. Users,
seeking advanced
features switch to the out-of-tree DRBD and use other means of communication:
Github issues, linbit's community slack channel, last not least
linbit's ticketing system.

That is why you see virtually no activity.

We use the in-tree DRBD with LTS (actually 5.15.32 and 5.4.188) and
depend on it. It just works. We never had any issues in the last 5
years.
