Hi Jesse,
While it's certainly true that it's impossible to bullet-proof Cordova,
protection against multiple inclusion is pretty basic. All the C system
include files protect against multiple inclusion. JavaScript objects like
jQuery include code to tolerate multiple inclusion. We should too.
The fix certainly does not require a large chunk of time! Here's the entire
fix; you put this up near the top of cordova.js, inside the outermost function
invocation:
if (window.cordova) {
return;
}
To appreciate why this matters, I think you have to cultivate a product
viewpoint. The Intel XDK is a development toolkit that attempts to make
cross-platform HTML5 more approachable. Obviously, as people get farther into
HTML5 development they will run into all kinds of hard problems. But right out
of the box, you want people to be able to put together simple apps simply.
That kind of good initial experience is a key to making an approachable
product.
This particular mistake, of including two <script> tags for cordova.js, is easy
to make and really hard to diagnose. In fact, some quite experienced
developers made this mistake and found it really hard to figure out how that
mistake led to the observed symptoms. You have to dig into cordova.js to
figure it out, and this is not the simplest piece of code. You don't want
ordinary Cordova users to have to do that if you can avoid it.

Hello and welcome (back?) Julian!
I have added you as an assignable user in JIRA, and assigned this issue to you.
You also should be able to assign issues to yourself now.
Regarding this specific issue, I think I agree with Joe's comment in JIRA that
this is probably not a bug. There are literally millions of stupid things that
people can do to their projects to break them, and I think if we fix stupid in
code, we perpetuate it.
Not a requirement, but I would recommend you share your proposed solution to
this before you spend a large chunk of time on it.
