Python extension license is MIT. Pylance license is closed source as shown here

Being MIT doesn't mean that it's fully compatible with VSCodium...

I agree but I'm not aware of any issue. I believe this was written in confusion because it auto installs the Pylance extension which is licensed only for GitHub and MS IDEs.

I think you cannot install Microsoft's Pylance extension in VSCodium but you can install Microsoft's Python extension.

In VSCodium, when I install Microsoft's Python extension, it also auto installs Python Debugger and Python Environments extensions.

In VSCodium, because I cannot install Pylance, I use BasedPyright instead (which I think that it is better than Pylance).

When I tried to use Microsoft's Python extension with BasedPyright, I think it works very well.

But like you said, it does not mean that it is fully compatible with VSCodium. I did not do any serious, in depth testing. So, there might be a problem that I don't know of.
