Thank you! What I believe does matter in terms of SEO is the speed and mobile-viewport optimisation. We recently received a notice from Google Console saying that they've switched mobile-only crawling for UNA.IO, citing that the site is responsive and is most likely to be used via mobiles, hence it makes sense to assess it using mobile crawler. Gotta be mindful of which blocks we turn off for mobile viewports (though it's still unclear if mobile crawler identifies itself as browser with mobile-size viewport), be vigilant about tap targets, do better with image optimisation (google is sensitive to suboptimal use of mobile data), etc.

It looks like Google AMP initiative didn't get enough traction, thankfully. I believe it was a bad thing for publishers and site-operators anyhow, but we'll be watching it to make sure nobody is missing out on rankings boost.
