It's a good question.
1. I agree that the docs should mention each other.
And the doc strings already do that:
`C-h v enable-recursive-minibuffers' says:
Also see `minibuffer-depth-indicate-mode',
which may be handy if this variable is non-nil.
`C-h f minibuffer-depth-indicate-mode' says:
This is only useful if
`enable-recursive-minibuffers' is non-nil.
But this hasn't yet been done in the manuals:
(elisp) `Recursive Mini' and (emacs) `Minibuffer
Edit' cover `enable-recursive-minibuffers', but
`minibuffer-depth-indicate-mode' is mentioned
nowhere, so far.
2. I agree that `minibuffer-depth-indicate-mode'
is useful when `enable-recursive-minibuffers'
is non-nil (generally and only).
3. I think I disagree that there should be
some kind of hard coupling between the two,
which would prevent users from getting
`enable-recursive-minibuffers' without
`minibuffer-depth-indicate-mode'.
It would be OK to automatically turn OFF
`minibuffer-depth-indicate-mode' when
`enable-recursive-minibuffers' is nil. But
that's not necessary (it has no effect), so
it's not useful.
I don't think we should turn `m-d-i-m' ON
systematically when `e-r-m' is non-nil.
That might be OK as a default behavior, but
we shouldn't impose it in a hard-coded way,
so that users have no recourse.
