@Amanieu @traviscross As discussed in today's @rust-lang/lang meeting, I already intended the language in the RFC to have the meaning you asked for, but the language around this had an ambiguous interpretation. To address the concern, I clarified the language around dyn-compatibility to make it more clear, and dropped the statement that removing final is always compatible.
(Filing this as an issue as an experiment as suggested by @nikomatsakis.)
