Does "not [] allowed" here mean "the table on disk is considered
invalid and ignored" or "the overflowing partition is suppressed" or
"the overflowing partition is clamped to the device size" or what?

I think the last of those is most useful, but the first one is the only
one I really consider broken.

Agreed.  I semi-regularly have a real use for overlapping partitions; I
would consider it a serious regression if they were to break.
