• Change local installation of libraries, instead of that, using poetry.

For what it's worth, I've regretted doing this every time I've tried it.

lol, yeah, the idea of that is basically make things easier to external contributors, i mean, i'm not the one who loves installing a bunch of packages in my own environment as it in the future can cause some conflicts.

Having a dedicated environment natively makes things easier and poetry helps that a little bit.
