Yes, it is.

I am not proposing changing in any way how we
develop and use Haskell parsers as tools.

I am proposing taking an existing parser and using it
in a different way.

Indeed. Easily finding and documenting such discrepancies is one
of the major benefits of having a machine-readable
component in the standard.

Agreed. I am not proposing that.

The machine-readable portion of the standard will be based
on a parser library that exists quite apart from the standard.
