I imagine anti-lazyloading extensions will start appearing soon.

And that's exactly why common API for lazyloading is awesome. It's a PITA to write such extension when everybody is using custom approaches for lazyloading. Once there's a common API, there will be a common approach to override it.

whole extension:

    document.querySelectorAll("img[loading]").forEach(function(e){e.loading="";})
