There doesn't seem to be a consensus on whether Xe should be used on older platforms, like Tiger Lake

https://docs.kernel.org/next/gpu/rfc/xe.html#xe-platforms

The common/gpu/intel/tiger-lake/default.nix module enables Xe:

hardware.intelgpu.driver = lib.mkIf (lib.versionAtLeast config.boot.kernelPackages.kernel.version "6.8") "xe";

But Xe won't be loaded unless something like this is configured:

boot.extraModprobeConfig = ''
  options xe force_probe=9a60
  options i915 force_probe=!9a60
'';

The jury is still out on Xe stability, some call it trash, others call it perfect

So, should Xe be force_probe'd for Tiger Lake in nixos-hardware? or should it be avoided?
