I simply don't trust Google to not change the rules later.

What will stop Google from down-grading 2nd class URLs (ie, not hosted with google) to page 2 results?

It's effectively the same thing as having no AMP at all, yet they cleverly got everyone on board with this tactic.

Edit: I just skimmed through this... this looks _WORSE_ than having Google show their domain. This is some of the sneakiest most deceitful garbage I could have ever imagined.

Just no way. Need convincing? Look at the animated gif half way down:
