What about the other way around?

For example, the Xbox One and PS4 didn't include emulators to run Xbox 360 and PS3 games because doing so would have fundamentally reduced the available system resources for doing new things.

Since Apple spends time making their new software work on old hardware, that either detracts from time they could have spent doing new things or commits resources to emulators to make functionality work on old hardware.
