Yes, but I can also put MS Word .docx files 'in a git repo', and diff them with MS Word proprietary version control. That's not good enough for use at work, in a software project among software engineers who don't need or necessarily want no/low-code; and it's not what I want in personal 'home automation' use either, which is where I gather it's perhaps most popular and how I discovered it - and probably most of that audience does want no/low-code and doesn't know 'what a git is', but, you know, I'm a SE, I know what git is, I like it, can't bare the idea of having anything like HA outside of its control.
Well, the node representation relies on internal identifiers and is not really human-friendly, so I think you’re out of luck there.
(I do run my home automation and quite a few dashboard and minimal API projects on Node-Red and version then that way, but if I want something with an actual lifecycle, I’ll reach for Python or Go…)
