I don't really see it, unless you name all variables like qListMyList.
As for comments it's not like the logical meaning changes. Besides, QList will have QVectors implementation anyway,
making comments or variable names that focus on it being a list illogical anyhow. (Besides QList was never a list to begin with)
Either way you'll have the same issues with API that is using QVector.
That would need to be changed to QList to be consistent.

A proper replacing is not done by replacing one type by another.
You'd need also adapt some variable and function names,
comments and documentation are silently broken.
There's also serialization to be considered, changes to log messages,
external tools operating on stringified type names, etc.
This is a significant amount of work for non-trivial applications,
replacing the type name scratches only the surface.

Not really. 'auto' saves at best the first mechanical bit concerning
the type itself. Variables, comments etc. will not be done that way
and will require manual interaction. It's very likely that this
work can not be done in a lot of cases, and application will simply
decide to stick to Qt 5.
I am *really* happy that this proposal came up.
