Romulas,It's not clear where you want to see zstd used. Here's a trivial patch to add Zstd to ‘guix pack’, if that's what you mean.
I didn't submit it in the past because I dread bikeshedding the compression level. -3 is the default, and compresses slightly better than gzip in a fraction of the time.
Kind regards, T G-R
