I'm not party to this discussion directly, but if we're discussing 
compression methods, maybe a completely different (simple, clean to 
implement) compression method is called for to replace both bzip and 
gzip in this capacity? I dunno. That's just my POV from the outside in. 
LZ4 perhaps? That's OpenBSD-compatible license-wise, though I know Theo 
is very much a bit of a curmudgeon on things like this.

Shrug. I hope a compromise can be achieved.
