You missed some call sites, such as:

if (!ParseScriptNumber(in[1], n)) return {};

typedef CPubKey Key;

To make a comprehensive list of the missing call sites from these changes:

  • thresh parsing
  • multi parsing
  • miniscript_string usage of ToString
  • the KeyConverter in the unit tests

From my branch which has this included in Bitcoin Core on which i could actually compile.
Looks good to me otherwise, nice cleanup!

Rebased, and addressed comments.

I've also made a few additional changes; turning inline "&& (num = ParseScriptNum(...)) &&" conditions into separate lines.

Checked the diff with my Bitcoin Core branch that i tested quite a lot. I didn't look for more potentially missed called sites too hard.
