I like that idea. <rant> Right now we're in a transition phase because I've inherited a horrible Puppet configuration that does unspeakably stupid/evil things. I actually have a rudimentary inventory script that polls puppetdb - eventually I'll put that monstrosity to rest, but for now it's convenient. Right now I still need to pass in the deploy_env variable because some configurations require it and I haven't gotten around to having the inventory script define them, but once that's in place I'll definitively go with your suggestion and make environment-specific inventories. </rant>
