In my experience, people want “it will work.” They will not accept “it could work” at all.
“It should work” is the perfect amount of hedge, even when you know “it will work,” because all of us have been burned by simple assumptions that were right 1000 times before and were somehow wrong this time.

They had plenty of time to decide on a better name.
