That works, care is needed if you go multi-boot as UEFI is a standard that is treated differently by different providers and naming collisions can occur.
e.g Debian,Devuan both using /EFI/debian, others using EFI/BOOT

One course of action to handle this is to have multiple EFI partitions.


Just to throw a spanner in the works because no-one has raised it... :)
Diskless linux workstations don't use '/boot'.
