Second, I don't agree that there are too many small modules. In fact, I wish every common function existed as its own module. Even the maintainers of utility libraries like Underscore and Lodash have realized the benefits of modularity and allowed you to install individual utilities from their library as separate modules. From where I sit that seems like a smart move. Why should I import the entirety of Underscore just to use one function? Instead I'd rather see more "function suites" where a bunch of utilities are all published separately but under a namespace or some kind of common name prefix to make them easier to find. The way Underscore and Lodash have approached this issue is perfect. It gives consumers of their packages options and flexibility while still letting people like Dave import the whole entire library if that's what they really want to do.

I'd suggest there ought to be config to disable source maps specifically, and specifically for either CSS or JS (not alwasy both), without turning off debug mode. As you note, debug mode does all sorts of different things that you might want with or without source maps.

There's not a way to do it at the moment without enabling all debug features.
