Let's make this a defcustom and name it inf-clojure-enable-eldoc.

"Var that allows disabling `eldoc-mode` in `inf-clojure`.

Set to `nil` to disable eldoc. Eldoc can be quite useful by
displaying funciton signatures in the modeline, but can also

Btw, this disclaimer is true for every command that does some code evaluation on the side. :-)

That's true, but all others are user driver. If you refresh a namespace or call doc, you understand that *1 and others will have been moved because you caused an evaluation. Eldoc is special because unbeknownst to the user those vars will change value. It makes using them very frustrating.

I'm ok with this, but it might be better to make the eldoc integration a no-op instead, so that people won't have to disable/enable inf-clojure-mode for the new config to be taken into account.

That was originally my solution, but that still leads to some problems. Eldoc is initialized as follows:

(defun inf-clojure-eldoc-setup ()
  "Turn on eldoc mode in the current buffer."
  (setq-local eldoc-documentation-function #'inf-clojure-eldoc)
  (apply #'eldoc-add-command inf-clojure-extra-eldoc-commands))

Since it clobbers any existing eldoc-documentation-function, once eldoc is initialized in a buffer there's no good way to go back to a clean slate since any previous eldoc function is gone. I'll add the enabledp function to the eldoc function so it would prevent more eldocs, but it cannot restore the previous eldoc unfortunately.
