Extrapolating that from "just us" to the broader audience we are hopefully targetting, it looks like lots of users/applications will be hit by these warnings and it will mean (lots of?) work for them.

Having a QList in one method and a QVector in the next one would only be confusing to our users. So IMO this thread should mainly be about deciding what the default name for this container is in our documentation and API in Qt 6.
Since you tell everyone since ages that QList should not be used (it's
in the documentation since 5.6:
https://doc-snapshots.qt.io/qt5-5.9/qlist.html#details , Marc wrote
about not using QList in 2010 ) and the discrepancy between std::list
and QList I don't understand what's to be discussed here at all.
