Err, of course not. Every backend is free to return additional kinds 
(that's what the completing-read approach is for), and whenever we find 
out that particular kinds get supported by many backends (or by most of 
the available/popular ones), we could "pull them into the core", adding 
a global command with one binding which would work across languages.

That's one of the balances to pick: both choosing a set of commands to 
support across the backends, and to allow frictionless extensions for 
special capabilities.
