Right. Absolutely. People should just follow some of these restrictions to get speed without AMP. I went down this AMP path though because of yes the Icon. Google was testing the Icon in Paid Ads I had read, and wanted to see if that could also improve our Click Through Rates. I also wanted to see if officially being AMP could improve things like our Quality Score in our ads, which would reduce our click cost, etc.
So yeah, just me trying to get blessed by G so everything else improves from G for us :)
