No problem, it happens quite often :)

That might be a question for Kevin, but on Debian a javascript library is 
treated as any other C/C++ library: source code should be there, the 
binary/minified version must be created from the unminified code at package 
build time (ie, when building the source code that ships it). It doesn't 
matter what uses it.

The same can be said about C/C++ 3rdparty libraries. So no, bundling is not 
good for distros. Imagine a security bug appears: we need to start hunting 
down each embedded version and fix it, checking that we don't break anything 
specially in forked cases. A nightmare.

But it's still a fork, meaning semi-duplicated code that we maintainers need 
to address.

Please allow me to be clear in one thing: I *do* understand that for Qt, as 
long as the license is respected, there is not much of a problem. What I've 
expressed here is what us distro maintainers face with this actions.
