I'd like to suggest to relax the "mandatory-ness" (yeah, I know that's not a word) of platform updates.
My suggestion is clearly motivated by the desire to be able to downgrade from a buggy update (like the recent 10.1.1), or simply from an update that happens to suite my needs less well than the prior version - but without the penalty of being cut off from application updates like I would be now.
I am a software engineer and I believe I could contribute to design such a solution. If the developers are interested in a technical discussion, just point me to the right place for it.
Either way, I hope you'll reconsider my suggestion.
