Understood. Does enabling range stepping unblock something else?

Offhand, the knee-jerk reaction is that if enabling range stepping
causes a regression, then it sounds like range stepping has a
problem that should be fixed and it may be premature to enable it.
I see a parallel here with all the all-stop-on-top-of-non-stop
work, which exposed a ton of such latent problems that were treated
as dependencies that needed to be addressed first. That's what
resulted in the creation of this test (see 'git log ede9f622af1f').
as-ns is enabled by default on native, but not on remote. It sounds
like testing with as-ns enabled on remote could reveal the same
range stepping problems, but all over the testsuite instead. :-/
