No, and everyone saying "move on to other things" is how pages slide from 2 to 7 over six months without anyone noticing why.
Your competitors dont stop. the moment you stop, your link velocity goes to zero and theirs doesnt. google sees one page going quiet and another still getting mentioned. guess which one it starts trusting more.
what changes is the volume, not the activity. i drop it to a slow drip, few links a week to the buffers pointing at that page, and leave it. with automation that costs me nothing, it just runs. the mistake is thinking link building is a project with an end date. its maintenance, like hosting lol
