Thanks for the carefully considered reply.
A problem with "x86 stakeholders" is that we've historically been
rather poor at finding our users and consulting them before making
changes. This has resulted in a number of flamewars, particularly
over type-based alias analysis.
It may even be possible to preemptively generate a flamewar with a post
to something like the LKML laying out the pros and cons.
It is a change to the de facto ABI. Think back to what happened with
the x86 direction flag issue.
