Custom Faces for Apple Watch

You have faces for Disney and the Pride and Pan-African flags. Where are the faces for other flags (American, UK, Mexico, Australia, etc.)? How about Christmas? Hanukkah? Halloween? Thanksgiving? New Years?

The face collection is pretty sad. I'm sure many people would love to have options for holidays or to show pride in where they live, at the very least. Right now you can only show pride for a couple social causes and a corporate entity. Apple needs to either make the options more robust or the door needs to be opened for third party developers. Are either of those things ever going to happen?

And I know you can load images into Apple Photos to create a watch face. That's not the point here though.
