I think the thread should remain Owen's, but the awards should be selected on an annual (or perhaps bi-annual) basis. There needs to be a proper award for the slowest build, as actually measured from start to completion, and interim awards for lack of progress.
If no progress at all is made in three years, then the project may be considered "abandoned", and only reappear as a contender when something is done.
I propose a suitability uncommitted committee to begin thinking about consulting on draft rules.
