Judging from history, that support will go away in a few years, like it did with PowerPC Rosetta after the switch to Intel. Correct. Rosetta is a transitional technology to allow x86 apps to run on M-series Macs while their developers work on Universal versions that will run natively on M-series Macs in addition to Intel ones. Apple has been clear that they expect the transition to M series chips to take about 2 years… a couple of years after that, they'll stop including Rosetta with macOS and will require developers to ship native apps.
