Configure unix socket

Hi,

Does jupyterlab support unix sockets? If so, how do I configure it?

It seems Notebook supports them (https://jupyter-notebook.readthedocs.io/en/stable/changelog.html#release-6-1-0) and tornado does too (https://github.com/tornadoweb/tornado/issues/2671). If this feature is missing, which is the right repo to log an issue for this, jupyter_server?
