We've been trying to kill off initrd in favor of initramfs for about two decades. I don't think adding new file system support to it is helpful.
Disclaimer: I don't know the background of this effort so more background might be helpful. Two years ago, I once thought if using EROFS + FSDAX to directly use the initrd image from bootloaders to avoid the original initrd double caching issue (which is what initramfs was proposed to resolve) and initramfs unnecessary tmpfs unpack overhead: https://lore.kernel.org/r/ZXgNQ85PdUKrQU1j@xxxxxxxxxxxxx Also EROFS supports xattrs so the following potential work (which the cpio format doesn't support) is no longer needed although I don't have any interest to follow either): https://lore.kernel.org/r/20190523121803.21638-1-roberto.sassu@xxxxxxxxxx Anyway, personally I have no time slot or even input on those.
