Yes, I think that we should not only add the parameter into
postgresql.conf.sample
but also

- add REPLICATION_SUBSCRIBERS into config_group
- mark max_logical_replication_workers and max_sync_workers_per_subscription
as REPLICATION_SUBSCRIBERS parameters, in guc.c
- move those parameters into "Subscribers" section in postgresql.conf.sample

The attached patch does these.
