A lot of really bizarre choices there.
With MauiKit essentially depending on KDE frameworks, abandoning Plasma 6 is a nail in the coffin.
I was never a huge fan of the NX design philosophy, because it felt quite disjointed, and not very well suited for neither mobile screens, nor larger ones, with how tiny yet spaced between everything is, but at the same time, variety is a good thing for people who did like it.
That being said, without first-party MauiKit support, Nitrux has no real benefits to offer, so it’s unclear what their plan is going forward
