It can't break the standards because you're adding a new syntax, you're not replacing one or hijacking the template token types.
For the rest maybe I can help but you seem to be more aware of
the latest standards than I am.
Also IMO this is really important in order to keep the standards
as clean and simple as possible.
I'd be willing to write a proposal but it would be a lot of work, so I'm curious whether people think this would be something good to have in addition to P0847, before I go ahead and write it up.
