I don't see what the problem is with having all plugins concatenated in one
file. I'd even go further and say that we should just concatenate all of it
in cordova.js (that is what is happening right now with core plugins).
We would not be disallowing people from having multiple script tags if they
wanted to. We would just be using one approach to solve the automatic
installation of plugins and I believe that re-generating a javascript file
is certainly easier and faster than editing script tags in html files.
People would still be able to manually install plugins, add script tags for
them....etc ITIZDAWEB.
