By the way ...

I just noticed in Mantis that I'd already filed something about bin
names.  I've just added as a note Swapnajit's question about bin names
as covergroup arguments; it is clearly related.

So this will have to wait until the next version of the standard.

Dave

I agree, this is out of scope, unless there is some other ballot item
that mentions these points.
