Mobile first is reality, and many of us are dependent of great SEO. Accelerated Mobile Pages seem to be increasingly prioritised in Google mobile results. There's currently no easy way to create AMP-compatible pages from Webflow, while there's better support for this in e.g. Wordpress.
Unfortunately Webflow and AMP have somewhat diverse goals (Great design & brand expression vs. speed and text content), but in the best of worlds, Webflow would add an option to have standard or AMPed mobile pages with semi-automatic, graceful degradation.
