I am a long time DietPi user (and supporter). It’s been almost 10 years now (started around 2017.
Its a great piece of software, I am always surprised why command line systems aren’t more like DietPi. It just works, while being minimalist, beautiful and intuitive.
Cheers folks!
Thank you so much for your ongoing, continuous support

Indeed, using Terminal User Interfaces to such extend is very rare, but I also find it a good compromise for users who are new to non-GUI operating systems => console usage, keeping overhead/dependencies for server systems still minimal.
