"Suitable for newcomers " and “handholding” are not the same.
Ultimately it depends on the user.
I have very little problem conjuring in my mind some ‘new user’ that can easily use manjaro.
Heck, my partner couldnt manually partition to save their life … but uses manjaro daily.
The point, as I see it, is that manjaro will not stop a new user from shooting themselves in the foot … while at the same time the system itself comes in a usable state with approachable documentation.
Manjaro is ‘suitable for newcomers’/‘accessible to newcomers’ … provided those newcomers are responsible system managers or willing to learn.
(none of which is to say ‘targeting linux newbies’ or ‘idiot proof’ or some other moniker)
