Now that we have template editors on wikipedia, it is no longer of any use to have tboverride for account creators, and they should be granted tboverride-account instead to avoid unnecessary risks.

There are 15 supporters and 0 people opposing this. It's not "officially" closed, but official closes aren't required. I think you can proceed under the assumption that community consensus has been established at this point in time.
(Consensus may change. This has happened in at least one other month-long, heavily-advertised RFC that gained unanimous support. However, there's nothing about an official close that can prevent that scenario.)
You're right; the discussion was formally closed by a non-admin less than an hour ago, in between when I typed the message and finally clicked 'Submit'. It's a known hazard of leaving tabs open for a while.
