util-linux will merge lastlog2, I have no idea about wtmpdb, this wasn't
a topic yet before my vacation.

procps-ng kills reading files directly and will use systemd, patch got
accepted but not yet merged.
The current patches for util-linux do the same.
I haven't looked at the latest PR for shadow, but they planned the same.

So nobody seems to care about "backward compatibily" with a time
where tools like "last" did not yet exist.

Is there a use-case, for which it is __reliable__ useable?

Until now, nobody could tell me one and nobody cared.
