It effectively makes the license "don't use this in an educational setting", unfortunately.
By yours, semen is perfectly legal in several countries (and a number of states in the US). That doesn't make it appropriate as a name in an educational setting.
Or, "Today we are going to be using Wine" doesn't need quite so much careful disambiguation.
Ah, yes, Illinois made semen illegal in 1923, as we all know. I now run around hiding from the cops.
