For instance in target database we do not have permission on some table used in publication,
but we still CREATE SUBSCRIPTION for owned tables.

I'm not sure, but it seems like only superuser have rights on all tables. I can't find any restrictions.

yes, i wrote simple patch. Role create externally, but it can be system role.
