From this thread (full disclosure: started by me) that arose from a question on another thread about commercial supplies being on the front page:

But I thought the whole point of creating opt-in searches for commercial supplies and vintage was to make Etsy *by default* a site for all things handmade.

We don’t yet have the opt-in searching feature or separation of the Commercial Supplies and Vintage items from the handmade items.

It may change after we implement that separation, but for now, all items in the marketplace have a fair shot at front page fame.

Also, Stella would not give a time frame for implementation of the opt-in feature.

I don’t really understand how it is that the Great Compromise of the Constitution (separate, but allow, commercial supplies and vintage on Etsy) has become a back-burner item.
