For example, why should Qt provide extensions that break encapsulation and increase the risk of errors?

I suggest to use algorithms which can work together with container classes at more source code places.

You did not address any of the concerns. You only added suggestions.

Imagine these methods become available in a future version of Qt:

I suggest to take another look for a clarification try around the topic “Checking the API status for the variable “Private d” of the QVariant class”.
