I don't know if being a FLOSS project leads to that. The only aspect I
referred to was the ability to learn how Qt works and to share any fixes
and changes with anyone that the FLOSS license grants.

any usefulness in QML. In addition, I suspect that if Qt got stripped
of a number of features it would actually improve.

Personally, I'm ok with the idea of Qt being C++ only, and only a GUI

The observer pattern isn't exclusive to Qt, nor is event handling. Qt's
way of doing signals & slots tended to be easier than the way callbacks
were typically handled. I don't know if it is still true today, as some
FLOSS callback systems which popped up recently, such as libsigc++, are,
in my opinion, superior to Qt's offering.
Qt's offering may be seen as a bit more resilient when dealing with
errors introduced by the programmer, but I suspect that this is mainly
due to the fact that some programming errors fail silently instead of
returning a long and nasty compiler or runtime error. This isn't
necessarily better or worse, as it can be seen as being both depending
on the scenario.

I was referring to how Qt applications look. Plastique looks nice, for
example. Qt also provides an interesting set of widgets.
