if you adopted vite from 1.0, you wouldn't have a need to change build tools in dozens of projects a year. Its really stable. Same with rollup. Webpack (was?) a little less stable, but it didn't churn at that rate either.

I'm just not sure where the churn is from. If you're talking about meta frameworks, like create-react-app, that churn alot and change things underneath, I get it, though with tools like that, one should always seek to stay on the happy path only, as its otherwise a recipe for disaster.
