Well, that's still the intent behind the commit that introduced support
for that. And since that went into a stable release, I don't see how we
could safely move away from CMA=0 means no cma= settings at all.

If you don't want to verify a proposed solution to the needs you
expressed, I suppose this bug report can be closed?
