To Bitcoin developers,
Who do you think you are to decide what's good or bad for us?
Why are you treating bitcoiners like a "nanny-government"?
Why do you stall for months patches and features to the reference client that are useful to all of us?
Oh please...
For a popular feature, nobody was willing to take the effort required to address problems with it, until very recently (too late for 0.8). Hopefully it will make it into 0.9.
Too short-sighted. sipa and CodeShark have been working on true multi-wallet support for a while, and that will hopefully be ready for 0.9.
Too dangerous for easy access - do you really want to enable people stealing coins from newbies? Power users can already import private keys using the debug console.
I agree this would be nice (in some form), but the filtering is inevitably a political move to try to force others to stop reusing addresses. While I think that may be necessary, it's arguable whether it belongs in the reference client.
Sounds like I need to get around to spinning a 0.8-based next-test release, though...
