Realize that the next version of Xcode and Swift will have all Intel binaries stripped out and will not be allowed to be uploaded into the App Store.
Third-party developers that don’t use the App Store we find their tools crippled by Apple and they will be forced to drop Intel as well.
Developers like Firefox, Google, Adobe, blackmagic, affinity, crossover, will drop Support like a hot potato. But will continue to develop Intel windows versions for many years. From Microsoft point of view this is good news, there are going to be many former Mac users switching in order to preserve their hardware investment.
What I’m surprised to see is the sheer size of the installer files for Golden Gate, I thought all Intel code was stripped out but here the installers are even larger than Tahoe, so much bloat.
