"Invite Me" API allows creating Group Public instances of private worlds, while the client and website don't allow it

Creating new public instances via "Invite Me" to private worlds seems unintended, because neither the VRChat Client (2025.4.2, build 1768) nor website allow creating public instances of private worlds.
Reproduction: Create a new group or grab an existing group's ID (I used a now-deleted grp_6102d838-c02d-44d2-a953-0c2211d025ab). Grab a world's ID. Craft an unlocked invite URL manually by hand. Invite yourself with "Invite Me" to create a public instance.

The API should've disallowed creating public/group public instances of private worlds, or both the VRChat client & website should allow this behavior.

Apparently this is by design. Duplicate.
