local caching without rewriting urls, ex <script src="//cdn..../../../"

Maybe I'm missing something obvious here, but how would you do this for URLs like the ones I showed, e.g. https://cdnjs.cloudflare.com/ajax/libs/normalize/8.0.0/normalize.min.css? Remember I said these files are for public distribution, and I can't rely on people having a local server - it's even possible to open the HTML files from the local disk (file://). Using the public CDN URLs is easy, and doesn't require me to distribute a bunch of extra files along with my own.

something like url_for('resource.js') in javascript or perl, to load resources based on configuration/environment

Sure, that's a possibility - but then that code gets run for everybody. This tool is really only meant to be a development aid, it applies only to the local git working copy, and only when it's configured by the user. The files in the repository are those for distribution, and thanks to the filter they always keep their public CDN URLs.

The only downside of the git filter approach that I can see so far is the small performance penalty on some git operations. So I'm not yet convinced that there is something wrong with this approach.
