Probably.

I'm not taking the approach that I as the designer should try to
produce a system in which all bad practice is impossible.
That can't be achieved anyway and leads to some undesirable
side effects.

I definitely agree with that philosophy. It was just a
for-what-it's-worth - if there were some added complexity to permitting
list values in candidate keys, it is not a feature many would use or
need.
