Dual use! (I looked up what dual use meant right after I posted this, and apparently it has military implications usually?) (The thing I'm trying to point at here is that we have limited resources, and whenever we can use a single thing for more than one purpose, it's good.) (Maybe the term I was looking for was dual-purpose? But even that doesn't really seem to map quite right.)
