Not everybody needs to work on the biggest problem, that's the "waterfall" approach to project management. If CPython was a single-developer project, that might be a valid criticism, but it's not.

For me that formalization is nice because they've brought f-strings into the PEG parser which can point at the precise location of a syntax error. I'm wary of the implications of arbitrarily nested f-strings for legibility... but oh well.
