Okay then. The proposal

- doesn't discuss alternate ways to solve the problem (including just
writing a lil' bit of library wrappers yourself to get closer
to the equivalent code you seek, or using code injection to inject the
boilerplate)
- doesn't explain why this problem is worth solving to begin with. In
the original message, even the paper author explains
having solved the problem differently, and then goes on to say "it
would be nice to have a language facility for this". Why?
Why do we need to have a direct language facility for every problem a
programmer runs into? Why is this language
facility more important and more common than others?

Hard Pass. No.

P.S. Somewhat tongue in cheek: I don't think the proposal has enough
keywords for use cases virtually nobody needs.
