It's not paradoxical at all. It would be a new implementation with the usual 
need for maturing even if it implements a well-known standard concepts.

And there is indeed room for actual experiments, e.g. when it comes 
structure layout. Pointer+int offset is not the only possible choice. 

You cannot do that in Qt proper, due to BC promises. Compile-time opt-in
is a way to exempt it from BC, but then your main reason to have it in Qt 
and not in Creator, namely 'more widespread use', is void, as barely anyone 
will opt in. You'll get more public exposure (with less risk!) if it's used by
default in Creator code for a while before the then-matured implementation
goes to the library.
