DeprecationWarning:

Base class for warnings about deprecated features when those warnings are intended for other Python developers.

Ignored by the default warning filters, except in the main module (PEP 565). Enabling the Python Development Mode shows this warning.

FutureWarning

Base class for warnings about deprecated features when those warnings are intended for end users of applications that are written in Python.

I think DeprecationWarning is a reasonable choice but I could see both ways. Devin chose the former. 🤷

I can’t see any deprecation actually, but if Devin will become the main maintainer, that’s fine 🤷🏻‍♂️
