Personally, I feel like the Emma zip should still be allowed, however the runs that use them should be put in a different category then the runs that don't use them, that way Windows 10 and 11 users still can compete against each other for times but for the absolute fastest runs Windows 10 users can submit their Emma zip run onto a different category instead of submitting it as the world record or official run.

TL;DR: Don't ban Emma zip users, just move them to different category.
