At first I thought it was a customization variable and that would make
it user-specific overwritable etc.  But I see now that evidently it is
not.  According to the docstring of d-m-m-handlers, eglot.el could just
just contain the above invocation, indeed.

But that has the downside that eglot.el must require "desktop.el" which
IMO opinion too strongly couples the two packages.

I think I like Lars's solution best.
