Exactly!
It's also a different kind of game design. 1e is closer to "dungeon survival," with 5e being closer to a narrative kind of game (with a clear emphasis on combats).
The 1e MU only does this if they find the right treasure, just as the fighter only lops of heads if they find the right treasure.
The 5e Wizard does this if they want to, and the 5e Fighter should be able to basically do stuff like this if they want to, as well. Magically manipulate minds, fire arrows that burst into energy, create illusions, conjure items out of thin air (or at least a magical sack), turn invisible, teleport, change shape, etc.
Give everyone those tools (more like 5e) or give no one those tools (more like 1e), but don't expect that you can put a "mundane" character without those tools in a game where wizards are promised those tools without seeing that discrepancy. It's not a problem of Big Enough Numbers or Enough Cool Options, exactly, it's more a problem of genre expectations.
