There's no point to pegging coins that are worthless into a system of also worthless coins, unless you want to test the mechanism of testing pegging.
As is, it's hard enough to get people set up on a signet, if they have to run two nodes and then scramble to find testnet coins and then peg them were just raising the barriers to entry for starting to use a signet for testing. If anything I think we should permanently shutter testnet now that signet is available.
