I should have been more clear, my apologies. When you write:

It's normal to wonder if this is true. Bugs created by equality inconsistencies would be so hard to debug! So few people will even consider the eventually of different equalities.

You're almost on the verge on saying "this is not a bug, this is a feature". But I'm suspicious of features that are that much unexpected. Many unique Swift features were abundantly commented and evangelized, and made their way in the Swift culture. Do you think this could happen for your suggestion?
