@alsutton That's a pretty uncharitable interpretation of the situation at hand. Compose Compiler is built on a foundation with no stability guarantees so it's neither JetBrains' fault when they make breaking changes in any version nor Google's that they strictly enforce what version they claim compatibility for.

Both organizations are collaborating to improve the situation but in the mean time I would rather have this explicit discouragement upfront than obtuse build errors towards the end.
