Let me make sure I'm understanding this correctly: in this particular
proposed solution, the side effect would be that we no longer have a
capable 32bit runtime which supports multicore parallelism?
Sorry, but I'm afraid this approach is pretty much unacceptable IMO,
for precisely the reason outlined in your last sentence. 32bit systems
are surprisingly commen. I have several multicore 32bit ARMv7 machines
on my desk right now, for example. And there are a lot more of those
floating around than you might think.
If that's the 'cure', I think I (and other users) would consider it
far worse than the disease.
