This code path can only be taken by normal backends, so that would
apply, still I don't actually see why we should limit us here on the
backend side.  If for a reason or another those two code paths begin
to be taken by a backend with InvalidBackendId, then users of the
session start/end hook will need to think how to handle it if they
didn't from the start, which sounds like a good thing to me.
