Okay, this sounds like good news.

I wish there wouldn’t be such massive chaos with every other language’s build system.

I will also compare it with the python3-flit module we have because that looks to use the pypproject.toml file, although there are several environment variables defined that I am not sure how to specify for my case but will see how things go.
