Don't forget that you can have platform specific bugs ;)
Ofc, just you know ... too much meat on bbq it will be quite degenerative :)
Actually, the API used is require('npm') that mean if it gets stable on OSX there will be quite 99% possibilities it will be stable the same on Linux and Win. Then templating and releasing will be quicker ;)
This is a beta release, due the fact we need to spot out many other possible and common bugs/problems before to make it really stable, that's the only reason why ;)
