"universal binary" is just a binary with multiple executables for multiple CPUs inside. Hardly unusual, it's been used for 32+64 bit before, and to package multiple flavors of arm.

Rosetta 2 is emulation in once sense, but it precompiles applications in to M1 code for speed.

Running all x86-64 mac apps plus iOS apps plus any updated / universal apps is pretty far from a software shortage.
