Sure, but I want to be on an older macOS and be given the option to use the latest Music or Photos.

For example, I'm probably not going to be upgrading to Tahoe until Sequoia's close to end of support life. I just upgraded to Sequoia last month from Ventura (decided to skip Sonoma since the various anecdotes of Sequoia made it sound like Sonoma-with-AI, with few apps breaking because of some new API change).
