[ANSWERED]Why is there a special Kernel for every OS?

Hi,
I was wondering why every OS (Ubuntu 16, 18, Ubilinux) gets a own Kernel by UP.
Why f.e. the Ubuntu 16.04 Kernel doesn't work with Ubuntu 18.04?
I get it, that a special Kernel is needed for the GPIO etc. But why can't one kernel be used for all Distros, like Linux?

    It is the same for every distribution, not just UP.

    Ubuntu has a kernel for 16.04 another one for 18.04 as the two distributions use a different build environment.

    Is it planned for the UP kernel patches to be upstreamed to the mainline kernel, so that Ubuntu 20.04 will include everything by default?

    The upstream process was started but not completed and at the moment we don't have a date for that, it definitely won't make it into Ubuntu 20.04.

    The kernel patches that can be upstreamed will cover all the boards except the original UP Board which requires a special driver that can't be upstreamed unfortunately.
