Sort of a "best effort" algorithm, I think. Am I > remembering that wrong? The current code uses a bare "git-fetch". I'm not sure what that defaults to if you're on a detached head.

But it may be that I am ignorant. I haven't dealt with any gitlink merges, but I think that supporting easy gitlink merges is orthogonal to this --remote option. For simple cases like "autocommitted submodule floats", one of the conflicting gitlinks will be an ancestor of the other, so it should be easy to automate that merge.
