Generally the amount of work should be equal, especially when, as in OPs case, the curation is already happening. But even when not already curating, what is effectively a simple rename could already prevent a lot of complaints: rather than automatically closing stale issues, you could either just have them tagged "Stale" and filter those out of your own view (if you prefer passively dealing with stale issues), or automatically tag all new issues as "Untriaged" and remove that tag if you want them to show up in your view (if you want more active curation).
