Yes, I was going to state the same thing. Hopefully your
screenshots illustrate why ElDoc, at least using its
its display methods available at the moment, is not
the best fit for this.

This is a very useful feature if done correctly, and I'm
leaning towards your approach of doing this completely
in eglot.el, so your code is an excellent start.

But the activation and other details have to be carefully
considered.  I will try to look into this soon.

Do you have a FSF copyright assignment, Chinmay?
