That's not entirely true in the case of IM. IM is a bit different
because it relies on servers and protocols (often reversed engineered)
which can randomly change. MSN (for example) are known to change their
protocol and after a while not allow anyone using the older version.

So a bug can "appear" later, which doesn't exist now. Which is awful
but quite likely.
