This is one that way too many people forget about, to switch to something else, you’d need to emulate x86 for the software that hasn’t or do without. Emulation causes overhead and performance reduction, and doing without seems fine on paper until you encounter software you want or more crucially need and can’t use it because it hasn’t been ported, isn’t open-source, or can’t be ported due to heavy use of x86 assembly.
Well, legacy compatibility.
