1/ Today, the frame-related legos are confusingly named.
Frames v2 will simplify this and make it easier to understand for users and developers.
Status quo:
1. Frames can appear in a feed and DCs
2. The Explore tab is permissioned and mixes "frames", "mini-apps", "actions" together; cast actions are siloed in a separate experience; composer actions have 2 different discovery experiences.
3. Frames that are called from the composer or a cast are called "actions"
