I understand that you have reasons for disliking this workaround, but the fact that a workaround exists is still relevant when determining what ought to be prioritized.

yes. so I covered this in my initial post:

"The next response, is that if you need this feature, then you can 'simulate it' by putting the class that needs this feature, into its own module.
However, the one-class-per-module approach, imposes its own new design constraint, and not one the programmer necessarily makes of his/her own volition.
It also does not necessarily follow, that a class in its own module, is there for the purposes of stipulating this constraint.
There are any number of a reason, why a class might be put into its own module. You cannot infer anything from that. You'd have to speak the designer to know intent."

I'm not at that stage yet.
I more interested in knowing what the others think about it.
I already know what 'core' think about it ;-)
