Not a bad idea, though I think in this won't work in the EU as Youtube
will try to display an intermediate page due to GDPR (not tested, I'm
not in the EU, I experienced a similar issue in the past while using a
VPN).  An alternative could be to use an Invidious instance, but this
might also be unreliable (I usually use yewtu.be, doesn't seem to work
for the Rickroll video for example).

It will also limit this info method to Youtube only.
