Well, yes. Now having a spell that is a limited expendable resource to do more than an always available skill is fair, but even besides that there is an issue. I think 5e is lacking is codified examples of what skills can achieve and at what frequency and at what difficulty, and a lot of how effective stuff like this is depends on the GM. Not that I think that stuff like skill challenges (that are easily usable in 5e too) are much better in this regard, as with them too it is up to GM what sort of skill challenge to attach to which fictional situation.
It would be a good thing if the 2024 DMG includes more examples and advice on using skills. When it comes to things like preparing a town for a siege perhaps there are some 3PP that discusses it, but this is not something that comes up on a regular basis. D&D simply doesn't revolve around this sort of thing. Modern D&D is centered around a small squad of people, not war games.
While it is quite a flexible game, there's obviously a lot of things D&D can't cover. Even the Dragonlance campaign didn't try to stretch D&D into this arena and instead just said "Play this board game". For better or worse these kind of edge cases are in the realm of the DM running the gam, therefore it's up to the DM to figure out how multiple PCs can contribute if they want.
