We are well into developing a new website using AMP, and are finding that some of our requirements are incompatible with AMP. For example the AMP carousel does not behave well when you try to display more than one slide at a time, so the designer is pointing out pages that do what she wants by using the Owl carousel, which in turn uses jQuery.
We don't want to take the time to rewrite all our pages to work without AMP, so is it bad to use jQuery on some of our pages that declare that they use AMP, but are not actually AMP compliant? Will Google penalize us for this?
I see different opinions. @Dan at Using amp script in non-amp page seems to think it's probably OK, but @pidabrow at Can I use AMP (Accelerated Mobile Pages) components/tags on a page that is not a valid AMP page? thinks the opposite.
