Neither I think, it's a side effect of good design and following
conventions.

I pushed the docchange to master as 15f4cdd873.

Yeah, I'd go with Dmitry's suggestion in

   https://github.com/joaotavora/eglot/issues/8#issuecomment-399698728

where he demonstrates that you can customize this by using:

   (custom-set-variables
    '(help-at-pt-timer-delay 0.1)
    '(help-at-pt-display-when-idle '(flymake-diagnostic)))

Though, in my testing, this always defers to eldoc (which is probably
the intended behavior).
