I think a clarification is in order: many of the things listed in those 
notes have also been discussed in other ad-hoc sessions (QtCore, 
QMetaType, etc.), and the resolutions in those sessions do not match 
what's listed in these notes.

Most notably:

* QList=QVector impact is yet to be evaluated in big codebases
* QString/QStringView/QLatin1String/u"" has no resultion, or better, it 
was agreed that has YET to be discussed
* QAny was proposed and rejected, instead the idea was to fix QVariant 
itself somehow
* returning std::optional for toInt() is just plain *wrong* and thus 
won't be done that way; it's at a minimum an expected type and really 
something even more complex (à la std::from_chars); and anyhow "how to 
port" is still a question

My 2 c,
