Just to be clearer, when I wrote "the npm stuff" I meant "npm and the tools
installed by it", so grunt, bower, karma, phantomjs, etc. Not the stuff
managed by bower, just the stuff installed by npm. Those npm-based things
should be packaged by the distros as tools, just like other programs the

Again, just so we're clear, yes, the above is *all* the components
installed by bower, including dependencies (jquery and requirejs being the
*only* dependencies not directly installed).
As I mentioned, the dependency trees in bower are significantly simpler
than npm packages tend to be (most bower packages have zero or one
dependency). The "100s" of dependencies are in npm packages - but as Martin
Gleiser has pointed out, npm solves that problem with its local install and
node_modules directory structures.
