OK nevermind. This didn't come up in my original search. So the fix is going to 
happen for parted, it's just a matter of time.

I will excerpt from this email:

This is the exact problem I mentioned earlier. parted's 'boot' flag has a 
completely different effect between MBR and GPT disks. Distro installers are 
continuing to set the 'boot' flag on GPT disks as they did on MBR disks, for 
linux boot partitions. This erroneously makes them "EFI System" partitions.
