Meh, too bad we have to use an emulator, it prevents any non-emulator supported platform from working. But LGTM, and tested that x86 -> aarch64 compile is working.

Yeah I agree; hopefully upstream fixes this.

There are extended instruction sets for some architectures that QEMU doesn't support, and p11-kit is nowhere near as important as access to those accelerators.
