It’s just stating a fact. QDataStream isn’t a generic cross-framework class, it’s not based on any standard. Its internal structure is completely undocumented. It’s compatible only with itself, and then, only with specific versions of itself. It even encodes the QDataStream format version in the stream itself.

So it’s not a step backward. It’s just a special-purpose class used for more than it’s designed for.

Personally I think using fstream or htons is perfectly fine. Both are portable, beyond what QDataStream does.
