Application developers _can't_ handle it.   Applications have no control over routing, and making applications do source address selection is a really bad idea.

I haven't encountered any ISPs that do flash renumbering, and I'm surprised to hear you saying that T-Online is doing it: that's not my understanding.   In general, providers that renumber their customers use graceful renumbering, not flash renumbering.   There's no reason to do flash renumbering.
