This isn't a knock but it's exactly what I was talking about and why I find OP's learning tool to be so valuable.
Lots of folks learn by example and hands-on labs. Personally, I'd much rather learn the basic ropes by jumping into a tool like OP's vs. finding/digging through all of these resources. I'll also criticize to say you likely already know much about systemd, and were able to pull/filter these resources much easier vs someone completely new to the concepts.
To illustrate further: vim is another tool that has outstanding learning resources, everything from very quick "hey get started" examples docs all the way up to adventure games. If I had to go back and relearn vim I would absolutely do it this way vs. digging on man pages like when I was a kid in the 90's. Personally, I learn by doing.

Overall - OP's thingy is what I would call a "rich interactive learning tool." It's anecdotal, and obvious projection - but _for me_, interactive learning tools optimize the time it takes to fully "grok" a subject from scratch vs. jumping into a bunch of docs/man pages.
