Will it? If we need to be able to “delete via X”, it sure feels more maintainable to have this feature supported via an explicit, named method vs. inlining it as an anonymous closure (as recommended by the “balanced” solution).

You can add deleteViaX later if you need it in the future. Usually YAGNI though.
