few libraries

and the framework must have the all needed classes

No it shouldn't and no framework possibly could.

thanks for your answer but in this way, I think there must be no helper and class in core library because each developer has a different idea
everybody that wants to choose a framework, searches for framework comparison tables and he sees that for example CI doesn't have auth library or REST library etc.

No, you choose a framework to set you up with a basic structure. It may come with some generic libraries that you are likely to need, but for everything else - there are thousands of libraries for all kinds of stuff that aren't tied to a specific framework

I suggest that put a survey between developers and put useful classes in the core library
during the time, by getting feedbacks from developers, you can improve it to fit the developers needs

You might as well suggest a global referendum to give every world citizen a $100k/year basic income. Things don't happen just because we want them.
