I agree. Topics like “how is the lifetime of a QObject exposed to the QML engine managed?” lack coverage and clarity. On the surface it is simple, but in practice it’s an extremely complex topic that has been a source for many bugs in our medium to large QML desktop app.

We contribute upstream a bit and we had documentation updates to clarify the stability of pointers to QHash elements rejected. ¯\_(ツ)_/¯

Personally, we superbuild bleeding edge Qt with the source code in tree so that it’s trivial to go to definition and inspect behavior. Makes the experience substantially better.
