Glad to finally have #Zstd compression enabled for #AlpineLinux's linux-firmware package exactly half a year (minus a few hours) after originally opening the merge request during our post-Fosdem #postmarketOS hackathon!
If you're running Alpine (or postmarketOS) and have all linux-firmware packages installed, the on-disk space will go down from around a gigabyte to around half a gigabyte or so, which I think is pretty decent.
