Yeah, I've considered exposing this from the C code, but was never super motivated about it. I go back and forth trying to decide if it's a bad idea or not.
If you want to cheat, you can use the version at _pydecimal._parse_format_specifier. The leading underscores should give you an idea of just how unsupported this is! But as far as I know, it works.
