Some background about this:
https://www.thkukuk.de/blog/Y2038_glibc_utmp_64bit/
https://www.thkukuk.de/blog/Y2038_glibc_wtmp_64bit/

procps-ng plans to support logind as utmp replacement with the next
release (4.0.4)

util-linux plans to solve all Y2038 problems including utmp/lastlog with the
next release:
https://github.com/util-linux/util-linux/pull/2168#issuecomment-1510968063
util-linux (lastlog):
https://github.com/util-linux/util-linux/pull/2164#issuecomment-1580331283
util-linux (utmp): https://github.com/util-linux/util-linux/pull/2100
The biggest "blocker" for replacing utmp with logind currently is, that you
need
systemd v254, which is not yet released.
Since wtmpdb as wtmp replacement is a PAM module, no code changes to any
project are necessary. So there was no real discussion yet.
