You already pointed me to that long ago. Surely, something
the like would be what to use in this case.

It's not that I totally want to forget about it. It's just
that I think with 7 days left until BETA I better start on
stressing the code and providing some docs instead of taking
care for possible abuse.

There are details that MUST be documented IMHO. For example
FOREIGN KEY needs that there is a UNIQUE constraint defined
on the set of referenced columns. Actually this requirement
is not checked in any way, so it MUST be mentioned in the
docs.
