@carsten why do you require the dev team to change its mind.
the new NS8 solution is merely offering the same functionalities of the old system albeit, considering that technology has evolved significantly since Centos7 initial release, and right now a number of projects and solutions are moving towards Automated Deployments and containerization.
In my understanding, what they are implementing and doing, is moving with the trends of technology, so that the software can offer a much better and longer EOL (LTD release) without major work on subsequent future versions.
I dont think @dev_team or NS8 in general is trying to compete with Proxmox or similar, as well as solutions like Truenas Scale. while they are aware these are potential competition on basis of current feature they offer, which somewhat colide in a small bit, it would be differentiated, byt being a single solution to handle a small business, or even a complex, large business, that needs interconnected solutions to just work.
