Hi!
There's something between the user level API and the ABI - which is source level compatibility.
That's a good point. We'd like to keep source-level incompatibilities to a minimum - especially for simple extensions, not like APC :) - but I agree it may be hard to maintain at 100% if we do engine improvements. Maybe we should have different criteria for something like APC (which is very deep in the internals) and something like memcached (which needs much less from internals).
