I wasn't aware it wouldn't build on the "pc" platform, but I never even
tried in the first place. The patch series definitely needs more
polishing anyway, but thanks for making me aware.

That cannot be helped, unfortunately. The current release has been
taking far too long already, and delaying it even further will
completely bar anybody from using LUKS2 with GRUB in the first place.

I don't really know about the release cycle, but personally I wouldn't
mind to accelerate it. That's only my two cents though as somebody who
hasn't been involved in the project that deeply.
