well some core pieces going away, like most of the legacy ISA APIs etc

the reason for a bumb is to do the things that we can't really do in our current model,
eg require bigger userland changes and general the change of what we support.

if the list is not long or if we end up concluding we can do it in the current model,
fine. but lets at least do the excercise. It's worth validating the model we have
once in a while ;)
