Yes. Still, there are ways to do it anyway, from Dosbox to WineVDM. Unlike MacOS where having even 32 bit app (e.g. half of Steam games that supported Macos to begin with) means you're fucked

You can use dosbox and x86 virtual machines just fine in macOS (with the expected performance loss) right now, without Rosetta. macOS is still Turing complete.
Technically speaking, you can run anything on anything since stuff Turing complete. Practically speaking however....
E.g. i have half of macos games in my steam library as a 32-bit mac binaries. I don't know a way to launch them at any reasonable speed. Best way to do it is to ditch macos version altogether and emulate win32 version of the game (witch will run at reasonable speed via wine forks). Somehow Win32 api is THE most stable ABI layer for linux & mac

To be fair, it's the emulation of x86-32 with the new ARM64 architecture that causes the speed problems. That transition is also why MacBooks are the best portables, in terms of efficiency, that you can buy right now.
All ARM chips have crippled x86-32 performance, because they're not x86-32 chips. You'll find the same (generally worse) performance issues trying to run ARM64 code with x86-64.
Rosetta 2 is pretty good at running x86-32. There's more registers on the destination, after all.
