The high compression levels of Zstandard are indeed a great fit for SquashFS, but SquashFS images are created in userspace by squashfs-tools. The kernel only needs to be able to decompress them. (Also, while Zstandard provides very good tradeoffs and will probably become the preferred algorithm for SquashFS, it's misleading to imply that users won't have to make decisions anymore. It does not compress as well as XZ or decompress as fast as LZ4, except maybe in very carefully crafted benchmarks.)
