not sure how above fits to my comment at all...
Connection re-use is not the real issue here, doing it senslessy on every
activate is..
And connect_if_none is a rather generic/undescriptive name and still would
not solve re-use if done in different method calls, so a rather for only
a very limited use case where one can just pass $conn around directly.
