OrioleDB is friendlier to SSDs and is de facto "the other" MVCC of Postgres. OrioleDB may be still be "beta" but that hasn't stopped operators/users.
MariaDB has some alternative MVCC, one of them is particularly outstanding.
SSD endurance at scale has on and off been a major concern for me, so I empathize with that. Others deserve to know of OrioleDB, and Postgres more broadly is probably better off for it too.

All of the problems Uber had, could have been solved back then, had they actually asked for help on the mailing list. Several of the issues they had have also been fixed/changed in Postgres itself as a reaction to that discussion.
