I ran into problems with sequences and I wonder if sequences-problems
are still expected, as the above seems to imply.

(short story: I tried to run pgbench across logical replication; and
therefore
added a sequence to pgbench_history to give it a replica identity, and
cannot get it to work reliably ).
