It would be nice feature if systemd could add another tag for the block
device that the kernel and initramfs are on, maybe systemd-boot so that
I could look for it and trigger other udev actions off that tag?

Thank you Lennart.
I'm thinking I will create my own sort of "built-in" command that can parse
/proc/cmdline to look for the root= variable early in udev rules so I can
create the tag.
So, systemd has to for determining the backing file system of some directory
and this is used by gpt-auto-generator for finding the block device
backing / or /usr/. I figure you want something like that?
We don't expose that directly though, and it's limited, since we do
not cover complex storage. We do cover btrfs though.
