Right.

  So a different verb would make that clearer.  Maybe

I also initially thought on these lines and came up with a name like
pg_convertsubscriber but didn't feel strongly about it as that would
have sounded meaningful if we use a name like
pg_convertstandbytosubscriber. Now, that has become too long. Having
said that, I am not opposed to it having a name on those lines. BTW,
another option that occurred to me today is pg_preparesubscriber. We
internally create slots and then wait for wal, etc. which makes me
sound like adding 'prepare' in the name can also explain the purpose.
