Nothing has been published, so a 1.0.0/2.0.0 split claimed a stability and a history that do not exist. Staying on 0.x says what is true: the API may still move. Under semver a breaking change is then a minor bump, which is exactly the relationship between the two lines — 0.1.x keeps legacy experimentalDecorators, 0.2.x moves to TC39 standard decorators. Branch renamed 1.x -> 0.1.x to match, along with its CI trigger and the maintenance-line notice in the README.
