Sorry for reviving this. Has anything been done by someone on this feature?
youtube-nocookie.com doesn’t link viewing activity to your YouTube account, so things like viewing history, recommendations, etc. will stop working.
This is absolutely a much more desired outcome considering that on a forum you may end up watching a video linked by someone else just because you are curious and ends up with good old Youtube inundating your feed with videos of that topic.
If nothing has been done, can someone give some pointers at what should this be? A plugin ( changing how the embed if cooked into the db) or a theme component (would it even work?)
