Poll regarding CI 3.1.x to CI 4.1.x upgrade

I'm writing something for the blog of the great @includebeer, https://includebeer.com/en/blog, about the beautiful work he did giving the example of creating an app on CI4. I am an amateur but I see that the big problem in relation to CI4, which was built from scratch, is that there was not only a technical evolution but a radical change, in my view, in the philosophy and objective of the framework.

Of course, you can use it in many different ways, but if you escape the main purpose of designing the framework, you will have many difficulties. It is no longer a tool of general use.

Still from my point of view, following a trend, for me, a little strange: frameworks are being used to create CMS applications. The CodeIgniter website is the best and a great example. All applications are "armored", hermetic, not related to each other, typically like CMS applications.
