Problem 1 is basic standardization and naming things. Hard, but possible.

Problem 2 is is solved by adding the deprecation warnings. The code works, but it generates warning messages.

Yes, it'll take some time, but I'd argue it's necessary. Unless you've memorized the entire standard library, remembering which functions use underscores and which don't (and which ones use "to" vs "2") is an unnecessary mental burden.

Deprecation warnings which many people will ignore, while new learners still learn with old material.

It is really tough and costs lots of energy.

If you have the energy: Create a complete proposal and push for it. If people feel like you it will go through.
