Style and layout issues aren't as pervasive as HTML issues, but if you ignore them you risk having your page disappear from the SERP entirely.
AMP styling is based on CSS but here again you face the problem of restricted and disallowed styles and the prohibition of external stylesheets.
In addition to this, you are required to include height and width attributes for each tag that is displayed, making your page easy to scroll.
Can you imagine how many hours it would take to insert these manually?... And then find out that you didn't have to do this since the AMP validator assumes values for various layouts.
Isn't it easier to focus on the ones that actually affect your page's performance?
