Sure... but
- using systemd inside the initramfs _may_ come at a later point
- even though the root-fs (and the resume-fs) is mounted in the
initramfs image... it may still interfere with the boot process by
systemd, e.g. when the later might accidentally try to re-setup such
dm-crypt mappings or else... which were already set up in the initramfs.
- all the questions, about whether systemd supports stacking of multiple
block layers is also interesting for non-root-filesystems.
