What cool idea am I missing with new Landing Pages in the campaign builder?

I like the functionality of the new landing page builder but it seems to me everything you need to have happen with a landing page is taken care of inside of the builder itself. Is there anything you “connect” the new landing page builder to like you would with another goal to a sequence?

I’m sure I’m missing some obvious cool ideas here, but I can’t think of a reason why I’d connect this to anything. It has the ability create new contacts, tag contacts, redirect, etc… I get that based on their submission/tag I would run a sequence but this would be handled by a tag goal, what good does connecting the New Landing Page goal to anything do?

What am I missing?

One reason you might connect it to a sequence would be if you were NOT applying a tag directly.
