Anyway, PS4 emulation isn't very affected by this.
Only thing it would benefit from would be that you'd be able to decrypt the firmware (and therefore run the emulator) without needing a hacked PS4 (like RPCS3 does with PS3 firmware).
Historically most people just pirate the firmware anyway (see: PS1 BIOS) so even there realistically it doesn't affect things that much. I consider this is a long-term, nice-to-have feature.
