> I can just immediately implement it rather than have it seat in a perpetually growing backlog of “maybe one day”.

My backlog for my side-project/business had a number of things in it that were frankly never going to happen. They only existed in the backlog so I could say they were in the backlog and add a note about who expressed interest in it so that, if it reached a critical mass, I could justify dedicating the time. That backlog is largely empty now. Things I thought were a pipedream or a "well, maybe one day if this gets bigger" became a reality.
