C4 came up with icepanel earlier. I will give one take - C4 is a nice abstraction that is very useful for architects, who spend a bulk of their day presenting things at different levels of the company.
When it comes to the engineers deploying and checking things into git, it is quite a bit of cognitive overhead. Imagine taking a C4 training and then referencing that knowledge every 4-6 months when you actually need to model something new, and having to choose layers to model at. Engineers are the ones expected to maintain system documentation, and usually they know exactly what the network and sequence diagrams for a system should look like. Anything standing in their way of that goal gets replaced with draw.io or even ASCII art editors. In my anecdotal experience building these systems - engineers want a dead simple graph editor that is canonical enough for their company (think shared templates); or they just haven’t fumbled enough with UML-metalanguages like this one enough to realize what they want.
That said, checking in models and having them be in a diffable format is helpful to them as well. There is no reason a visual editor can’t do this.
