Your last line applies to me too.

Isn’t one of the touted strengths of Clojure that if you want to do something your way, you can make a library, and you don’t have to wait for or rely on the core language maintainers to accept it as canon?

So whether or not your proposal makes it into core, you can still put it out there and people can still make use of it if they find it useful. Specter looks like a good example of this.
