IMO, there is no need to created WDOGE just like he said the main idea to create a wrapped token-based backup fund on a different chain most of them to avoid a fee transaction and yeah you don't need to sell your coins into ETH while you are using this. DOGE is already a cheaper coin and most of the use-case DOGE only for alternative transactions, you are talking about mainstream adoption for DOGE.
DOGE is a meme coin there is no use-case at all for DOGE because a meme ~XD, did you know the wallet DOGE? yeah the wallet still using the old wallet and make the transaction or node have some problem. Here one of the testimonies from Freebitco about DOGE :
We closed Doge down because it was never profitable and we were encountering more and more problems with the Doge core software being unreliable. The code hasn't been maintained for many years there is no hope that will ever get sorted out. There has been a long delay paying out final withdrawals for the same reason. Our Doge node crashed and required rebuilding. The latest update I have is that it has finally stopped crashing and is about 50% way through resynching the entire Doge blockchain.
