We already have zlib, bzip2, and xz in base. zstd is just one more that fills an important niche. If you're not familiar with it, zstd is a relatively recent new compression algorithm that provides a better compression/performance point relative to zlib at any point along the -0/-9 curve. It performs favorably to bzip2 and xz as well, although it's not dominant at all points relative to those two. See the last figure in https://clearlinux.org/blogs/linux-os-data-compression-options-comparing-behavior for a better idea of what niche it fills. Thanks, Conrad
