Yes, they are.

The replacement for QtXml are the streaming classes in QtCore. They've been 
available for 10 years.

There is no replacement for the XMLPatterns module.

Yes, definitely, for as long as we ship them plus 5 years.

No. Deprecations are only irrevocable when we want to get rid of code that is 
in the way of making progress, such as the QList discussion. Those two modules 
are not in the way of anything else, so the decision can change.

All it takes is someone stepping up to maintain either or both of them.
