Sure. It is a ridiculously common to ask a dictionary if it has a record for a
particular key. It is much, much rarer to ask one if it has a particular value.
Lists, tuples, and sets, on the other hand, only have one kind of interesting
data, the values, so the __contains__ method operates on values with them.

Practicality beats purity, in this case.

Not in my experience.
