I don't know how into building organizations you are, but 18f succeeded. they had a small footprint, and outsized impact, and really good relationships with the rest of the government. That kind of effectiveness is really difficult to grow in a massive bureaucracy. If your goal is efficiency you try to nurture that success.

throwing it away and starting over for purely political reasons is a completely negative outcome. the best you could hope for is to replicate what it was, but odds are against you.
