Can I say that this is just a very, very stupid statement? You're venting and 
ranting, not contributing to the discussion.

Let me deconstruct it for you:

1) First of all, problems with UDP are not new with Qt 5. They've been 
happening for years with Qt 4. The turnaround time for fixing the bugs is 
neither better nor worse now.

2) UDP problems are not exclusive to Qt either. There are bugs in the OSes 
too, ranging from subtle incompatible behaviour to outright stupidities. Like 
I said in another email, at one point on Solaris SO_REUSEADDR had the opposite 
effect of everywhere else.

3) Competencies do not migrate very well, or at all. The people who work on 
QML and graphics hardly ever work on networking. From the past 8 years of Qt 
development, I can count in one finger the number of people who have done both 
networking and anything graphical. That means any emphasis put on graphical 
progress neither improves nor detracts from networking abilities. Or core, for 
that matter.

4) The number of people working on networking is more or less the same as it 
has been for the past 6 years, ranging from 2 to 4 people. The difference is 
that there's more code to maintain now, with QNetworkAccessManager and the 
HTTP complexity inside.

5) Finally, the existing market is still supported. In fact, it is better 
supported now than it was from 2009-2012 (Nokia era).

All that worked in Qt 4 continues to work in Qt 5. GPS wasn't part of Qt 4 
(that was Mobility and most of it only supported the Nokia platforms); 3D 
wasn't part of Qt 4 either (Mobility again). Qt Quick 1 continues to work 
exactly like it used to. As for widgets, there are a few known corner-case 
regressions (session management, for example), the code is mostly unchanged.

In summary: I dispute *everything* you said in this email.
