Casual players like me tend to be cool with undo. It would be fantastic if the matching could include a setting - something like "forbid undo" which would allow the hardcore folks to go at it. The problem is that you never know what kind of person you are playing against, and it really spoils the mood when someone takes the game too seriously. Especially when there is an obvious mis-click that doesn't impart new information.
There will always be folks that abuse undo, so I think it's important to allow for the denial. But some light screening in the matching algorithm might prevent a lot of games where people come in with completely different views on what they want out of the game.
