I doubt Metro will make that call, because the use of expansions and planning everything is part of the strategy. Plus, just because it's fall/winter doesn't mean plants can't grow. That's what the use of greenhouses and/or planter bowls are for.
A player's failure to research gardening is as much a part of their strategy as another player's remembering to do so.
It is, of course, up to the challenge team, but that's my take on it.
