Engineered microbes are almost always far less fit than wild-type. They will survive best in a monoculture, and if they are forced to compete with less hobbled strains they will usually find a way to get rid of the engineered modifications in order to grow faster.

True
But the article did not address this, it should have.
It will be the big question before deployment

I've always wondered how quickly this effect would ruin the monoculture.
Suppose you're treating the engineered microbes like sourdough starter: Add them to nutrient solution, wait for desired effect, take a small sample, add to next batch.
You'd expect a selective pressure away from the engineered outcome, such that after X batches, your samples are overrun by wild-ish type mutants. But is that a merely academic concern, something that might happen after 500 batches, or are you out of luck by batch three?
