Here's a very late comment on this.

I'd consider it a corner case, so I'm not sure it would warrant this in
itself. But it's not intentional behavior that I'm aware of.

That said, tracking when a subscription happens could also be useful for
other cases I think it might be worthwhile doing.

Correct, there is no code in place for that.They show up on the admin
dashboard for manual handling.
