In python it's pretty common to have LSP separate from type checking separate from linting (e.g. ruff+mypy+ide_specific_lsp).

Which to be fair sucks (as it limits what the LSP can do, can lead to confusing mismatches in error/no-error and on one recent project I had issues with the default LSP run by vscode starting to fall apart and failing to propose auto imports for some trivial things for part of the project....)

But it's the stack where pyright fits in.
