We haven't run into performance problems around this, but thank you for surfacing it! There was some discussion around whether this was needed, and the consensus was "in theory it would be useful, but in practice, who knows if it's actually necessary?"

Seems like you've found a case where it is! I'd post specifics of your use case on github.com/elm-lang/virtual-dom/is... - ideally with a link to the D3 code in question.
