I agree that some kind of support should continue. But in the case of an email app, focused on simplicity and ui design; not feature sets for power users, i dont think this expectation can reasonably consist of new features. On the other hand: the value was in the ui design, not some dificult technological challenge. If there is actually a viable market here, chances are more than one player will follow in their footsteps. UI designs are easy to copy. And until then, the kind of support one can reasonable expect, will continue: bug fixes.
