Peoplemight find that surprising, so the "ALL TABLES IN" was intended to future-proof against surprising behavioral
changes.

Yes, it appears the syntax was chosen to avoid one kind of confusion, but created another kind. Per the docs on this
feature:
FOR ALL TABLES IN SCHEMA
Marks the publication as one that replicates changes for all tables in the specified list of schemas, including
tablescreated in the future.
Like you, I wouldn't expect that definition, given the behavior of GRANT with respect to the same grammatical
construction.
