The opinions of developers about low code solutions are not very relevant.
Low/no code solutions exist for when there isn't enough time or budget for a developer created solution, which is to say, pretty much all always. In the real world of business problems, almost nobody has access to a professional developer.
I suspect as with most things in education, they focus on small self contained problems because it's easier to teach and easier to grade. These toy problems end up being all students know and therefore are what employers select on.
I'm a little confused by this comment. It feels like you are complaining about the problems that are solved by configuration management and infrastructure as code, yet you seem to reject it as too complicated.
All the problems you raise are solved by infrastructure as code.
To understand how ancient this is, the Worshipful Company of Carmen's history began in 1272.
For US audiences, this operated as something like the DMV, hundreds of years before anyone had thought of such a thing. Over time obviously, these functions were taken over by a national government agency, but as the Worshipful Company of Carmen had had hundreds of years of history until that point, the traditions were kept in ceremonial form.
