Hot take: Making new backpacking routes isn't always wrong
Last summer in the Wind River Range, the main loop was packed with people. I watched a group leave it to go over a bare, rocky hillside. Everyone says this ruins nature, but there was no soil or plants to damage. I believe if you choose areas with hard ground, it's fine. The real problem is too many folks on one route. Spreading out can reduce wear and tear. It's not a simple right or wrong issue.
