I don't know whether conclusions based on history are appropriate in this instance, because (as I recall) no previous version of OS X has resisted fading away as has Snowy...Apple has never before faced the prospect of disenfranchising as large a portion of its user base as will be affected by their dropping its support in the near future.
I dunno… Maybe they anticipated this taxpayer revolt and decided "Damn the torpedos...", but the free Mavericks upgrade makes me wonder.
At any rate, I think the bottom line is that as long as Snowy can sync iOS devices it'll be considered supported by those in need, and they, and the rest of us recalcitrants, will invoke "Damn the torpedos…" as respects everything else if Apple insists.
