I find it hard to believe that there are installations using
more than about 3, and even there you can bet they are changing
a lot of other parameters.
I don't think it's that rare as logical replication also needs a walsender

help.
Here is where this change was originally discussed:

The low semaphore settings on some BSD systems were also mentioned
there. Did anything change now that it is triggering more issues now?
