My strategy for dealing with the new upcoming COPPA rules (as in, be able to make game trailers / soundtrack uploads with cartoon characters, bright colors, etc, without potentially getting sued) is to use the "18+ viewers only" feature on all my Youtube videos. Will this lead to any issues with using them as Itchio project trailers?

After bulk-changing all my videos, I tried viewing one of my project pages, and the embedded trailer loaded fine without presenting any sort of "hey are you at least 18?" question, but since I have no idea how the embed works behind the scenes, it would be nice to have a confirmation that this doesn't lead to any technical issue down the line (and doesn't automatically add an "NSFW" tag to everything I've made that has an embedded trailer or something to that effect).

(When checking whether this worked, I used Edge instead of my default browser to get as little host poisoning as possible - the video gets blocked on Youtube unless I'm signed in but loads like normal from within the Itchio project page)
