If the term SAAS wasn't already so taken, I suspect that the generalized term would be 'Scripts As A Service' instead of FAAS (which might slot into your brain differently). In the same way you might write a number of small utility scripts piping data between each other for various purposes, you can do the same with FAAS. You just also get the benefit of not having to manage infrastructure, crazy amounts of scale, etc.
