Just yesterday i had discussion about this with people in the lab. I can't say that i heard something new regarding this, and not saying that i'd like to resurrect the discussion. So, in short: there was no objection concerning getting rid of isXXX in favor of using #is: method. The only thing which still looks controversial is too simple default implementation which answers false.

No so. I think #is: is a terrible idea, and I object to it on those grounds. I only object to the default implementation because it's the thin edge of the wedge which invites people to use an anti-pattern.
