Hi Christoph,

It’s not completely clear what you’re asking for here.  If the API 
matches what’s in zstd-1.4.6, that seems like a reasonable way to 
label it.  That’s what the upstream is for this code.

I’m also not sure why we’re taking extra time to shit on the zstd 
userspace package.  Can we please be constructive or at least 
actionable?
