I've just heard this... Do you agree that every POV character in a novel should make some kind of meaningful journey? (like a character-change, lesson-learned, etc.)

I hadn't really thought about it. My current WIP has the MC with a major journey, two minor POV characters with fairly major journeys, and two minor POV characters that don't really change much. I'm wondering if I should rewrite to give the latter two some sort of journey (even if it's minor), pick new minor POV characters (one of them sits right next to another character that has a major journey, but isn't actually a POV character), or delete those POVs entirely.

Or, does it matter? Can I have POV characters that just give a better sense of the world (I'm writing a fantasy) and provide a perspective to the reader that they wouldn't otherwise get?

What are people's opinions on this?
