- Updates getRolePermissionBlobs, which is called from the migration-related function legacyUpdateRolesAndPermissions. It's important that we support thick threads there so migrations don't break on them
- Introduces getThickThreadRolePermissionsBlob, which is called by the above, and will be called in a later diff to get the permissions for thick threads
Depends on D12656
Can we extract this to its own line? Similar to how we want await to be visible, I think it's good for hooks to be as well
