Ok for me if you meant it this way.

I'd boldly reply to that that if one is unwilling to reason about a
piece of code, one should not be fixing it.
But I'd also agree that the code should be as readable as possible to
get a many developers to contribute.

Back to Qt current situation I think that the lack of comments in some
parts is a bigger throwback than
the code style.

And back to the actual topic of Qt/STL containers, I am for option 3
if the project can afford the
extra development and maintenance otherwise I'd go with option 4.
