OK, I'll consider Alexey Kondratov's set of patches as the current
state-of-the-art then. (They still apply.)
I found a problem where I'm not sure it's a bug:
The attached bash script does a test by setting up pgbench tables on
both master and replica, and then sets up logical replication for a
slice of pgbench_accounts. Then it does a short pgbench run, and loops
until the results become identical(ok) (or breaks out after a certain
time (NOK=not ok)).
It turns out this did not work until I added a wait state after the
CREATE SUBSCRIPTION. It always fails without the wait state, and always
works with the wait state.
Do you agree this is a bug?
thanks (also to both Alexeys :))

PS
by the way, this script won't run as-is on other machines; it has stuff
particular to my local setup.
