That's the core issue.
An RPG doesn't have to reset. However without resets, it won't be able to grow nor keep up with the changes in the RPG market.
Especially after the invention of the internet.
CoC doesn't need to reset. But CoC is niche and small in the market.
And even CoC had some relatively radical systemic changes, they just came kind of slowly at first. But compare the current edition to CoC 1e and you'll see some sharp systemic changes in some spots.
