Thoughts
If the sublime text community is receptive to the idea of pyproject.toml’ing everything, I can help do that and use working_package_manager.
If not, I think I switch to Zed. My other options are, go back to PC, maintain my own forks with pyproject.tomls, or update WPM with the ability to do the copying and subpath manipulation that pyproject.toml needs. I could definitely do either of the two latter, but it would just make me sad, I think. I suspect it would be more fun to switch to Zed than maintain a house of cards on top of the Sublime community’s inability to innovate.
