[swift-evolution] Ownership on protocol property requirements

Today these keywords have no meaning inside a protocol, so clearly it
should be an error to use it in that context. I agree with Jordan that the
error should be on the protocol.
It's entirely a different conversation whether the keyword should have
meaning or not. If it should, it seems to me it should be limited to
protocols that are limited to classes. But that's an additive feature we
can discuss later.
The source-breaking bug fix that is more pressing today is removing
meaningless keywords that can be misleading to users, because they have no
effect but look like they should.
