It is trivially easy to validate the existence of a cited paper.

I'm sympathetic to the idea: we should have an open, publicly queryable citation graph. Google scholar could very easily offer this at marginal cost near zero, but they won't.

Of course, you do need an API key and it took quite a while to get it last time I needed it, but it's there.

I'd almost rather Google scholar not offer that, because it might draw attention from the eye of sauron and deliver them to the Google graveyard.
