yes, getting rid of qt containers is easy. only the qtcreator plugin
would still need them (and it's a good question where to draw the lines
to not introduce unnecessary conversion inefficiencies).
qstring is a lot harder ...

bootstrapping qt classes is counterproductive (you notice latest when
you link libqbs into qtcreator) and laborious (you notice latest when
you get to qprocess or another class that *needs* full qobject/moc and
the qt event loop to operate sensibly).
as of now, there is no reasonable alternative to pulling in random
external dependencies, possibly boost (fwiw, the relevant c++ stdlib
projects are apparently dormant).

for the js engine, a bare JSC was considered.
hmm, come to think of it, the js engine might not be the only part from
webkit (or webengine) that makes sense to build upon ...
jake had started that "qt-free qbs" project (he got as far as
eliminating (most) use of qt containers), but it was snuffed out because
it was unrealistic and counterproductive at that time. even now, no
patches in that direction will be accepted unless a coherent final
picture and a credible committment to further maintenance is presented.
