Version 10.3.0 shipped a breaking change in a minor version

Version 10.3.0 dropped support for the legacy architecture, which is a breaking change, but this was released in a minor version update. This release should have been done as version 11.0.0.

You're right, it's a breaking change. It was announced ahead of time in #3978 — v10.2 added deprecation warnings, v10.3 was stated as the removal version.

This pattern is happens in the RN ecosystem — Reanimated drops older RN versions in minor releases as policy, react-native-screens dropped legacy arch in 4.25.0. Doesn't make it strictly correct, but it's not unusual either.
