So how will people know what the anchor is for, or realise to click on it? Also, what will sharing a content by other means do? Such as sharing an AMP page via a built in IOS mechanism, such as the built in mechanism to share on Twitter, for example? At first glance, this all sounds like a terrible 'solution' - although I may well be wrong of course... I'll have to see it in the wild to really pass any kind of real judgement I guess...
