I found that I could enable LZ4 compression for initramfs on my vivid machine by installing liblz4-tool package, adding one line to mkinitramfs and installing a kernel compiled with CONFIG_CRYPTO_LZ4=y.
Please include support for (legacy) LZ4.
Attached patch includes changes made to the latest version (initramfs-tools_0.120ubuntu3).
