I somehow missed the magic word "limited" in the OP's article. I think
I confused his "declaring controlled types at other than the library
level" with "unlimited", so when I read your article I saw the
problematic aspects of the unlimited version which you report instead
of the good aspects of the limited version.

Your "limited" library indeed works just fine.

Apologies.
