Yes as said before all thing where is x86_64 supported. So core-dual.iso and netinstall-dual.iso will be 20MiB increased.
Optionally we can include this feature only on core-x86_64 and netinstall-x86_64, cutting EFI support from both dual.iso.

Anyway long time ago, we talk about iso sizes, and conclusion was: do not care anymore about CD-ROM, at least for dual ISOs.

efibootmgr will be included if this is added.
