Based on the test failures I've been seeing for months and tried to
address in the original patches (not all of which are due to an
unexpected HOME setting), it feels like that's probably too optimistic a
conclusion in the general case.

A lot of the relevant tooling places its configuration directly under
HOME for example, not under XDG_CONFIG_HOME.

I can also imagine user-specific settings affecting some of the
auto-formatting functionality tested in eglot-tests.el.
