The reason it conflicts is because it seemingly used to ship /usr/sbin /update-initramfs, See: https://bugs.debian.org/729809. Other than this alt dep, it looks like parts of plymouth would need to be merged, and dracut patched for plymouth not being in /usr.

Debian seems to be using "Depends: initramfs-tools | linux-initramfs- tools" for almost every relevant package. See also bug #1108987, which is about the fact that dracut shouldn't conflict with initramfs-tools.
