Switching to the same wallet is a rather minor compromise in my opinion for what seems to be a better solution to most other proposals.
I'd agree since it's compared with method where 3rd party is required. But it could be major compromise if the wallet isn't actively developed where the security is questionable and it could be discontinued anytime.
things like this proposal don't have to be a full wallet since all they do is creating a scriptPub that is not common. so they can simply be another feature in the already existing wallets. if the wallets didn't add the feature it still can be built on top of them. for example with a very small amount of code it could be built on top of Electrum. that way it doesn't really have to change/maintained over time and it still relies on a wallet that you may trust.
