They were first introduced ina058598eccand then carefully moved in648e0bb242, but it looks like they were never used by any external code. This code can be useful on the server, but the server has its own params package to deal with parameters. Clients usually create Parameters and then get results as stackitem.Items, so they don't use this code either. So there is zero point in keeping it.
