I own the company, and the issue came to my attention in a 1:1 with an engineer last week. I can decide and communicate what the policy will be, and the matter will be settled. The hard question as always is what constitutes a good policy! What happened here was that a well-meaning and talented designer passed a Figma along to the dev team and the Figma included these Lottie things and a note about how to embed a chunk of js to display them. It caught the dev & myself off guard because neither of us had even heard of Lottie but I guess it might be getting popular with designers. Considering that there actually seems to be an animated GIF embedded in the Figma file, I don't really know the intimate details of said designer's workflow and I think we just need to tell them "This Lottie player thing is not going on any website we produce, but an animated image certainly can, so is it prudent for you to alter your workflow? What is the optimal handoff step?"
