This code seems to be fairly pervasively AI-written (both structurally/syntacticly, with many additional AI verbosity tells in the documentation, and going by the commit history).

That's a problem for me, given what this library does: arbitrary transformations of Python code at load time. The fragility, security risk, and complexity added by basically writing a subdialect of Python with new semantics is something I'd like to see more human attention on and maturity of before I consider using it. There are times when AI smell doesn't concern me much when deciding whether or not to use someone's code. This isn't one of those times.
