No, the official fix doesn't break anything for me.  You're correct, I
currently have no use for such a class, but I don't see why a "classy
ABC" cannot exist. However, on second look, "super(classy_class,
classy_class)" still isn't going to work 100% in the hypothetical case
where there are more metaclasses to deal with, so my change is
incomplete.

I was going through diffs and, in the interests of library code,
thought I'd post it.  Without an actual use case, it doesn't matter
whatsoever; feel free to ignore.
