afaik ZSTD support is rather new and I wanted to have maximum flexibility when
reusing the initramfs, even with older kernels - i.e. being able to mix a
ptxdist-built initramfs with older kernels. I opted to also support zstd, to
allow booting future initramfs' on current kernels, should gzip support ever be
dropped in the future.
However, I think we could probably drop the zstd support, if you are concerned
about image size.
