ALL abstractions are leaky - this is an objectively true statement.

As others said it's not for beauty, it to make sure if there is abstraction it fits the problem. If there is encapsulation it doesn't get in the way. For some coders they can get it on the first try and there is no reason for them to rewrite code. For the rest of us mid coders we need to explore first as well as make sure all cases we desire for Lib/API work.

You're right, I should have been more clear, all abstractions are leaky, but some are right enough most only notice occasionally.
