I don't mind `#:`, but I'd prefer to write `[#:foo 5]` rather than `#:foo [foo 5]`, that is, I don't like the repetition of the name (I first came to Racket precisely to avoid repeating code).

When I expressed that a few years ago, I was told it would be unlikely to change in the future though, which is perfectly understandable given how deeply this goes.

make-keyword-procedure  helps with that specific complaint - you don't need to introduce a formal for the keyword value.  But it doesn't help with my complaint (symbolic "existence" keywords) because Racket requires a keyword to have an accompanying value in the argument list.
