Sure, but the point here is that if for example users have
client_min_messages set at least at warning, they may have no idea
that an underlying slot has been created. This is a confusing
experience for users.

As subscription is a self-contained concept, it seems to me that any
errors happening should at least try to do some cleanup action before
just giving up processing, that would be a less frustrating
experience.
