CHANGE: Deprecate useIMGUIEditorForAssets by K-Tone · Pull Request #2283 · Unity-Technologies/InputSystem

K-Tone · 2025-11-14T14:42:37Z

Description

Here we deprecate the useIMGUIEditorForAssets feature flag.

The aim is to reduce total variability caused by having to keep code that can work both ways - with uitk and without. We've had the uitk code running for a while now, and with the minimum supported Editor being 22.3 TLS we no longer have to care about the case when uitk wasn't available.

Might this even be ValueTuple to reduce object allocation?

Thanks for making adoptions. It was small but I do not see why we should introduce shadowing scope risks / warnings when we do not have to.
