Thinking more about it.  It's now not difficult to add a gcwq for an
unbound pseudo CPU number and use it as host for workers which can run
on any CPU.  The automatic concurrency management doesn't make much
sense for those workers, so @max_active can be used as the explicit
concurrency throttle.  It's not even gonna take a lot of code but I'm
just not convinced that there's much benefit in doing that.  So, yeah,
if necessary, sure, but let's think whether it's gonna be actually
useful.

Thanks.
