--- Pyright isn't usable for GLib/PyGObject based libraries. Both
--- python-lsp-server and jedi-language-server which are based on Jedi and work
--- for GStreamer/GLib etc. are extremely slow for Python files with 1000+
--- lines. So we only enable completion, rename/hover and document highlight
--- support. Jumping to definition takes seconds in large files, so we just
--- rely on in-built support or perhaps that comes from treesitter.
