I don’t know if there’s any right or wrong approach here.

For instance. It’s certainly nice that Windows supports its entire back catalogue. It’s also nice that MacOS has been able to reap the benefit of deprecations, breaking changes, and even 2 architectural shifts.

Though I do think something that’s often missed in this debate are the specific challenges that mobile brings that set it apart from say, the console environment, that really do require a more ‘cooperative’ and ongoing approach to the platform.

Your device really will perform better and present a more cohesive experience if apps can be nudged onto that new privacy API, or an old threading API deprecated and removed.
