Ah, I get it, so ess-mode does something different.  Then
maybe it should also set eldoc-documentation-strategy
to something sensible.  Eldoc-documentation-strategy is
just the new name of eldoc-documentation-function.
If you find an `ignore` there, you're safe to change it
, buffer-locally, as you did before.  Maybe you should
even do it even if you _don't_ find an ignore there.
The fact that it's now defcustom doesn't change much
in my opinion, I don't see defcustom's as off-limits to major/minor
modes, as long as the user is still given override power
in the mode hooks.

Alternatively, ess-mode should just use the old interface.
It's still available and functional.

But I think you should select a strategy that suits `ess-mode`'s
functions.

Hope this helps,
João
