Yeah, that might end up being a false economy for superscalars.
In general, I wouldn't recommend spending too many cleverness beans on
non-Zba+Zbb implementations. Going forward, we should expect that
even very simple cores provide those extensions.
I suspect you under-estimate how difficult it is to get the distros to
move forward on baseline ISAs.
Ya, we haven't even gotten to the point where most implementations are
shipping with the B extensions, much less to the point where we can
start ignoring all the pre-B hardware.
