Same here. Would be very sad to lose Wine capabilities as well, and presumably these have minimal macOS dependencies.

Wine can run on aarch64 with FEX reasonably well already, no special instructions or hardware acceleration required. There's a bit of extra overhead, but that shouldn't be a problem for old games on modern hardware, they should run about as well.
Interesting, do you know if performance is roughly comparable with Rosetta 2, i.e., are we talking about a few percent of overhead or something more dramatic? (For CPU-bound code; I understand that the overall effect will be smaller due to GPU code probably being executed host-side in native code etc.)
FEX isn't done yet, but Valve's people seem to suggest an overhead between 10-20%. Not great for getting the most out of a CPU, but small enough to compensate say the difference between an M1 and an M5 chip.
