does that make it truly valuable?
some would call this god's work
You don't even need a devtmpfs in the initramfs environment, and it may or may not even persist into the fully booted system. I believe Systemd has a tmpfs unit file, and OpenRC has a service for it which is enabled by default.
I made my own CPIO library: https://github.com/desultory/pycpio and one of the main goals was this behavior, so I could create CPIO archives with device nodes without privileges. It's really as simple as writing some bytes to a file saying "when you extract this, create this device node". It's not like any archive actually has a device node, just instructions for where to put them, and what properties they have.
Certainly, you can't extract these archives as non-root, but you have to go out of your way to make an initramfs have non-root privileges.
It's mostly made to work with Gentoo (uses pax-utils for finding dependencies), but should work with any distro. It does most of the initramfs creation process rootless. The main consideration is that you need privileges to make device nodes, but I just create them synthetically within the cpio image.
On most systems, this tool still requires root to copy the mount binary.
