XTAJIT, which is the x86(_64) application compatibility layer on Arm Windows is far from garbage, and got a ton of engineering work. The problem is that having a 30% performance penalty on a Snapdragon 8cx (because Arm only started really caring about fast CPUs starting from the Cortex-A76, which is the first generation stemming from that effort, resulting in not-ideal perf characteristics for x86 emulation) results in not very good performance. This can only be fixed through better, smarter Arm hardware. (which is coming)
