Thanks for the pointer on using "nil", I had forgotten about that.

Since it appears I'm failing to make a convincing argument, I think
that using "nil" will be my approach going forward.  I'll avoid using
mode-based configuration in Eglot, as I find it deceptive and prone to
future breakage.  In its current state, I think it would be wise to
discourage its use in the user manual, to avoid misunderstanding and
potential future problems.

I'm surprised nobody has raised this issue in the past, but don't be
surprised if you receive additional bug reports in the future.
