Question: Purpose of unused language servers in `languages.toml`

[jbirnick]

In languages.toml defines some language servers which are not used in the defaults.

For example, it contains the pyright and basedpyright language servers. But they are not used as default language servers for Python, and in fact they are not used anywhere else in the repo.

[language-server]
pyright = { command = "pyright-langserver", args = ["--stdio"], config = {} }
basedpyright = { command = "basedpyright-langserver", args = ["--stdio"], config = {} }

What's the purpose of this? Does it allow me to add the basedpyright language server more easily compared to language servers which are not at all present in this file? If so, how?
