Huh? In service of what? There’s not all that much inherently good about backwards compatibility, but you’re really implying that deprioritising it is a misdeed. If I wanted to use an OS that prioritised backwards compatibility more than macOS, I’d use Windows, and suffer through the downsides of that trade-off. I’m happy using an OS that balances things in a way that’s more in line with my priorities.

This isn't backwards compatibility though - the example in the post here is a major bug in an actively supported API.

Apple dropping support for old things over time is a reasonable philosophy, but Apple breaking current things unintentionally and then neither fixing nor communicating about it, primarily because they don't actively engage with their ecosystem in general, is a problematic choice on their part.
