It has not.
We are carefully analysing, aren't we? But facts are facts: the deadline
was April 1st for new modules. Therefore, no KDE CRYPTO module for KDE

They are not equal.
But for *my* purposes as an encrypted socket class, it is enough. All I
want is encrypted communication. I want KDE 4.0 to have both https
support in ioslaves as well as IMAPS/POP3S or STARTTLS support.

Let's get it straight: KDE 4.0 will not have smartcard support. Period.
KDE 4.1 might.
And you're basing your conclusions on what QSslSocket is now, not what it
can be. I still don't buy the argument that it can NEVER EVER support

What part of "I wanted a secure socket class" did you not understand?
Mailody is using QSslSocket without any certificate store or policy
management. This is obviously not acceptable for a release. It's using
QSslSocket for the simple fact that I wrote
QTcpSocket *socket = new QSslSocket(parent);
somewhere in ksocketfactory.cpp because I thought "hey, that would be
nice". That feature is not documented so, technically, no one should be
using it. In fact, I plan to remove it, just to make sure that QSslSocket
doesn't get widespread use before we implement the rest of the support it
needs -- if we choose it at all.

Yes, the user community will wait another year. They will wait for KDE 4.1
because 4.0 will not have smartcard support. We have no CRYPTO right now
and, logically, no application can be using something that doesn't exist.

Two things are guiding the management:
1) "He who does the work decides"→ no one has done the work in the 2 years
that KDE 4 is in development
2) KDE 4.0 is not the end of KDE 4.x

You are quite quick to jump to conclusions, aren't you?
No, I am not in favour of any solution. Right now, I am pending more
towards to QCA, but I can still change my mind.
I am not afraid to say that. It wouldn't be the first time that KDE
applications are prohibited from using a Qt class. That happens with
QHttp, for instance. During KDE 3 times, QSocket was also off-limits.
We have not made that decision yet. And decision = code.

You're not making friends with that assumption.
