In Emacs 29, if you somehow manage to upgrade Eglot to >= 1.14 (cough
bug#62720 cough), you'll find it's also better.

Right. That's a good sign it itself.  Here, have some more patch:

  (setq-default eldoc-documentation-strategy 'eldoc-documentation-compose)
  (add-hook 'emacs-lisp-mode-hook
    (lambda () (setq-local eldoc-echo-area-use-multiline-p 1)))

Then go on with elisp your life and maybe peek into M-x eldoc-doc-buffer
once in a while.
