< Remove PiP Disable Attributesについてのフィードバック
Hello. Sorry, not possible with userscripts. You should checkout my extension, PiP Unblocker, it currently removes Feature Policy, but I will update it to the new Permissions policy soon.
Forgot to link it. (+4 months later)

Can you add the interception of header policy and remove it ?
Permissions-Policy: picture-in-picture=false
