I think, Slime only adds the ":" when it parses features expressions
in source buffers, not for the message from the wire.

Yes. By convention, messages on the wire should only contain
keywords, nil, and t. But this convention isn't enforced, and the
:new-features message obviously violates the convention.

I'm not sure what you mean with "interning" here. Instead of
including the symbols in the message we could send a string
[e.g. created with
(let ((*package* <keyword-package>)) (prin1-to-string <new-features>))].
Are thinking about something else?
