I think one major difference is feathers - we have not had feathers show up in any mammalian mutations or evolutions that I know of. We went a different direction, with the fur and all. So even if fast tracking wings were possible I think that would involve some kind of fur covering and different adaptation for flight more akin to bats.
Another major hiccup is - fast tracked uncontrolled evolution, aka genetic mutation, without the controls/failsafes (such as non-viable mutated animals dying out and failing to breed) just equates to cancer…
Both of those functions have been available via key fob for at least a decade, no internet required. Though yes the range on that can be limited.
