I've found Rosetta works really well with VMs using Apple's Virtualisation framework, to the point that I've not had any issues building niche proprietary x86-only C++ libraries like network card drivers. The only annoyance was spoofing uname -m and/or setting architecture build flags everywhere since build systems will try to target arm64, but actually getting things to build was far less painful than I thought it would be. I'm thoroughly impressed.
