Why not? A major reason that premium domains even exist is because the second-hand market for squatted domains meant that some domain names have sold for literal millions of dollars; and otherwise that domain is sitting as a dummy advertiser page trying to sell itself. Old registries weren't able to participate in that process themselves without also owning a registrar that participated in the same competition; but, a few decades of hindsight means the newer TLDs are going after potential earnings that Verisign never got a chance to have.
