What you have described about Mageia capabilities is too high level for any non Linux to understand but a very good explanation.
Me thinks all operating system have their own weakness , advantage and disadvantage.
[[ Android is an open-source platform that designed for different devices, especially tablets, Smartphone, and watches. It is based on the modified version of the Linux kernel and other open-source software. ]]

In Linux, the user has access to the source code of the kernel and alter the code according to his need. It has its own advantages. Bugs in the OS will get fixed at a rapid pace. ]]

There are no such thing as a 100% secure operating system that is so perfect that your data is 100% secure.
Windows, Linux, Android etc. operating system all have their own terrible aspect and nobody have ever create a perfect operating system. It is totally impossible to design an operating system that is 100% secure, perfect, without flaws and have the most superior features.
You already have an old Mageia 4.0 or 5.0 that can run on 32 bit PC system. Therefore it is not necessary to have the latest Mageia that run on 32 bit system. Just upgrade Mageia ru on 64 bit is just enough.
Mageia is also based on Linux kernel. Therefore it is possible to design Mageia to function like Android OS with their application software App, but Mageia App will be for personal computers and laptops. Why you cannot design Mageia operating system like this way ? Is it too much work and need a lot of manpower ? If Mageia is open source and many developers who can access Mageia source code and create all kind of App that make Mageia interesting.
Do you need a lot of manpower to maintain Mageia App system ?
With Mageia App, you do not need to spend time thinking how to provide any software solutions at all. Just let the developer create the Mageia App to solve all software problems and create interesting App.
