Well, ideally, it would be called 'target remote' ;-) Having two different modes,
where one mode has strictly more features than the other, is a way to have
one of the modes bit-rot.

Likewise, I think it's better to always use async mode,
if the target supports it. We're not at the point when we can do
it -- even with my patch, 'target async' has a couple of extra
failures relatively to 'target remote', and I never tried getting
test results for linux native -- but I think having async mode
always on should be end goal.
