Actually they did change the before in a not backwards compatible way at least two times (IIRC), so there should not be much pain in doing that again... At least from the updates/compatibility preserving point of view they have it sorted.

Can you point to a link describing this? As far as I remember they were still bundling the old runtime and feeding older code through the older runtimes.

Yes, I think that's correct, but I don't know the details of how was it done. The point was that they have done this before and the new design isn't that old actually.
