Interest in a lower compression iso optimized for USB booting?

Thanks Dbohdan. I have experimented with Zstandard compression too. It does seem advantageous, but as DSL sits right now it is just slightly too big to get onto a single CD using it. For USBs and VMs I think lz4 makes sense because it is still faster to decompress than Zstandard and in those applications the increased size isn't really important. If I manage to trim down DSL a bit more and get the room inside 700mb it would be nice to offer Zstandard compression instead of xz.
