I'm wondering about that, too.  If you're trying to do logical
synchronous replication, then maybe there's some argument there,
although even in that case I am not sure it's actually necessary.  But
if you're doing asynchronous logical replication, it seems not to make
much sense.  I mean, walwriter is going to flush the WAL to disk
within a fraction of a second; why would we wait for that to happen
instead of getting on with replicating the next transaction meanwhile?

(There may well be an aspect to this I'm missing, so please forgive me
if the above is off-base.)
