OK, then we just keep xz.
Do you think full zstd support will eventually happen?

I like to at least add support for generating them because I think they
are slightly nicer than xz archives. About the same size/compression,
but using less resources, cpu at least:

$ time unxz ./binutils-2.42.50.tar.xz 

real	0m1.374s
user	0m1.289s
sys	0m0.082s

$ time unzstd ./binutils-2.42.50.tar.zst 
./binutils-2.42.50.tar.zst: 333670400 bytes                           

real	0m0.228s
user	0m0.231s
sys	0m0.082s

Admittedly it is just a second, but if you do 60 CI builds a day, then,
ehe, you saved a minute...

Cheers,

Mark
