rd.luks.name in cmdline

This discussion is still ongoing.
When dracut decrypts a LUKS-encrypted volume it expects /etc/crypttab to contain its name [1]. However, this file is not used by OpenRC [2] and duplicating configs just for dracut can be wasteful.
A short solution would be to add to dracut.conf:
kernel_cmdline="rd.luks.name=<crypto_LUKS UUID>=root root=/dev/mapper/root"
This way, UUID is only mentioned once. Contrary to [3] this works (I use it). However, rd.luks.name is documented for systemd [4], but not for dracut. Can I add this as a small "LUKS" section for OpenRC people?
