This seems to get to the heart of at least one issue:

A purist approach worries a lot about identity and equivalence.

A more practical approach is concerned with utility. If it is useful to 
assert that two classes are equivalent, then maybe do it, but be aware 
that problems may arise later, because the two concepts were 
independently developed (and owned) by different people who have 
different views of the world.
