And tbh it's not only a matter of distros that already use it. Arm itself has the SystemReady specification [1] which mandates the use of EFI in most of it's flavors (SR, ES and IR). Keeping in mind U-Boot's EFI support is very close to be 100% compliant, I think it's beneficial overall to have pre-canned board configs that support that.
