That's also an aphorism that may or may not correspond to reality.

Not only there are companies with highly capable teams that are able to move fast using a complex mix of technologies, but also there are customers who have very little interest in new features.

This is the point of my comment: these maxims are not universal truths, and taking them as such is a mistake. They are general models of good ideas, but they are just starter models.

A company needs to attend to its own needs and solve its own problems. The way this goes might be surprisingly different from common sense.
