I actually don't think it's that unreasonable to get notified when
system-wide processes like the autovacuum launcher or the logical
replication launcher start or stop.  That's stuff somebody might want
to know.  It's not going to generate a lot of log volume, and it might
be useful, so why suppress it?

Where things get ugly is if you start to get a high rate of messages -
e.g. from starting and stopping parallel query workers or other kinds
of things where you might have workers starting and stopping very
frequently.  But surely this isn't an example of that.
