@jcteague can you explain here or in a discord Strapi Community call what you want to use the feture flags for depending on your answer I mind know an other solutuion.
Since I think it is better to do the feture flags fully in strapi.
Main issue I see with launch darkly is that you would have to do some wired stuff to make it work with content-type changes. in the strapi backend or code changes to an endpoint.
