All servers utilizing Intel VROC (https://www.intel.com/content/www/us/en/software/virtual-raid-on-cpu-vroc.html) are unable to install Ubuntu due to this limitation.
MD RAID metadata and all these assembled RAID arrays usually contain a GPT partition table that the UEFI systems can read (possibly by using the copy on the end of the disk?) so it works fine to boot the systems once installed.
The current problem is that it's not possible to install with this limitation in subiquity (and possibly grub). This seems to have worked fine in for example 18.04 (per https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/ssd-software/VROC-Ubuntu-Setup-UserGuide-342787-US.pdf), and I would as such call it a regression.
Please put back space bar heating (https://xkcd.com/1172/).
