The code itself looks fine. However, since this feature introduces a breaking change to the default behavior, it would be best to include a feature switch for it in the current release—disabled by default. We’ll highlight this in the release notes and plan to either enable it by default or remove the switch entirely in a future version.

Makes sense — I’ve added an optional switch to handle this case as suggested.
