That drop-in replacement aspect is very convenient: it would probably not be hard to find applications for an accelerated QVector (or so) that speeds up things like calculating a CRC with minimal effort (and most of the time without adding a library dependency).

Note that there is no surprise in that you'll find many drop-in replacements for STL containers or algorithms, intended for various purposes, but nothing like that for Qt, because the former APIs are standardized.
