Seems a perfectly reasonable example to me, even if fabricate is more like middle levels than high level, it's only going to come up once you reach higher levels. That is, when you're only level 7 (first level you get 4th level spells), blowing your one and only 4th level spell for the day on fabricate unless it's an enormously important usage--otherwise, you'd save it for something more potent, right? But when you're, say, level 16? You've got three of those slots sitting around, and for Wizards, Land Druids, and Clerics, you can probably even refresh the slot afterward. Blowing one of your 4th level slots on fabricate at high level is water under the bridge--even though doing so makes the Fighter's background and context meaningless.While I agree with the overall point, I am a little puzzled at your choice of example. First, fabricate isn't particularly high level (4th). And, are blacksmith montages a thing?
Spells being able to obviate entire chunks of another person's character is and has always been one of the greatest weaknesses of the 3e/5e model. Needing to micromanage your spellcasters so they don't dominate entire scenes is the main issue there. The fact that 4th level spell slots go from "extremely precious, do not waste" to "no big deal" is a big part of that slide from "powerful but limited" to being...well, just powerful, few limits.
