Sure. But almost any product starts our being something that changes rapidly &, over time, the rate of change slows down until it pretty much stabilizes.
(Of course, with software, much of this process actually plays out in the market. With books, much of it happens before it reaches the market &--depending on the kind of book--hitting the market can mean that it never gets to finish stabilizing. RPGs seem to be somewhere in between.)
It's then that the marketing people step in & rationalize further change. (^_^)
