ACK returning Coinbase for the moment. (Also agree with removing webwallets in general, though.)
When/if Coinbase is removed, it should be for a legitimate reason and fairly applied to other services, not because they simply are doing experimentation that does not affect their public production services. The latter should be encouraged.
Inclined to agree with this. New users should be taught that having Bitcoin means you are responsible for holding your own private keys. So in a sense, using any webwallet is less like using Bitcoin than an alternative client where you still hold your own keys. Some people may not agree with alternative clients proposing changes to the protocol, but that's still no excuse for failing to maintain impartiality. If the other webwallets stay, Coinbase should stay. No one has to right to say what clients Coinbase can or can't use, so excluding them because they are using other clients is just petty and a sign of insecurity. Attempting to hide the existence of things you disagree with will only continue to increase the general suspicion and mistrust that seems to be pervading this issue. It still baffles me as to why some decide to be involved in an open source project when they stoop to the level of not allowing other people to choose in an open and unbiased manner. I've argued before that this only damages you own cause and I stand by that.
