Yes, a mailing list is much better for discussion.

In response to your point about duplicate derived instances, yes, it
would make derived instances different from explicit ones, but as I've
argued before, I think it's unavoidable:

If you accept that this is the primary use of the standalone feature,
such conflicts will happen all the time.
