Yes.  Create Advantage is the action to establish a fact as true.  The ability to use that fact for an invocation bonus is just gravy, IMO.

Strategically, sure, the focus might be on the bonus.  But narratively, CaA is all about "establishing facts".  And as that is realized it becomes a much more popular action.

I was joking with a friend the other day, saying that "create an advantage" is a misnomer. It should be "create the story."

Well, I think the action, and properly the verb, is Create. It's just that there's a blank following that that must be filled. Create Advantage; Create Story; Create Truth. Create Wall of Fire, Create Slippery Footing, Create Great Word of Mouth.

I use an example in one of my games about the power of aspects. In that example, I explain that someone who has the aspect "Stand Up Citizen" could not use his sneaky approach to pick a lock, because they wouldn't know how. They're stand up citizens after all. Unless of course they had previously used their clever approach to create the "Looked it up on Youtube" advantage. They can do more than just provide a free invocation. They an also be used to create permissions that might not have been available otherwise.

I didn't learn this lesson until my campaign concluded, but its a huge revelation once you pick up on the story impact of the "Create" action!!

Definitely went through this change in focus myself.

And, just to reemphasize what +Jack Gulick said. I think too many players focus on the +2 bonus. That's why they don't use CA as much as they probably should. Especially in a game with weapon bonuses, if I'm already getting a +2 to damage, making two attacks seems a lot better than a CA and an attack. Of course, that kind of "pure math" logic only works if you ignore the story potential in CA.
