Because that means yet another build tool users have to maintain, check for security updates, etc. Packagers for people not using guix will need to start including it, etc, which will just add to the absolute excess of build tools out there. Currently installed on my system are bsd make, cmake, gmake, and scons, just to handle various software I've installed. Plus, you have samba in there that drags in Waf for its builds, and I know that there's some package out there I'm gonna want to poke at that's gonna wanna bring its buddies ant and/or nant in to party too. Unless the new and improved tool can understand all those tools, it's just gonna add to the mess.
