This thread has run it's course. KaOS has set clear goals right from the start in 2013, one DE, focus on one toolkit, one architecture, again see the links:
Focus on one DE (KDE Plasma), one toolkit (Qt), one architecture (x86_64)
It targets users who have tried many Operating Systems/Distributions/Desktop Environments and have found they prefer a Distribution that uses all its available resources to work on one DE to make that the best it can be, and know that after their searches, the best for them is KDE Plasma.
Of course as noted (always) a distro making choices is not for everyone, so you have the option to choose from hundreds who do not make such choices. That has nothing to do with a power user, any power users can do whatever needed within a certain DE.
As noted before, the OP does not want a distro that has made a choice for one DE, so no need to use KaOS.
