You could say the same about a model (or any function) running in R. Want to instantly convert it to a web service? Use plumbr or RestRserve packages for that. Want to make a quick web application around it? Use the shiny package for that. Just because Python is good at X, doesn't mean other languages are necessarily worse at it.
