AMP-sites currently need to be created by either a cms supporting it (joomla, wordpress, contao, typo3, etc…) or by hand. Furthermore, to achieve this rather the theme/stack devs are in charge than realmac – just because amp got some restriction compared to ‘traditional’ html. also, some features won’t work at all.
Means -> all current themes and rw-cms systems are incompatible with amp, i guess most plugins and stacks too…
What you actually could be used for amp (if there were themes supporting it) -> the styled text plugin.
So those of you dreaming to use AMP as mobile version of your website -> stop dreaming. AMP is not intended to wok that way, its rather made for (and by) news agencies, publishers etc.
Its made to make access to news easier and more distraction-free.
And regarding that ‘AMP is always on top’-stuff. Well, most times news are on top, most people nowadays access the web with a mobile device -> if an AMP-page is available, google will prefer them over the default mobile view (of the same site) cause it grants a better ux. But you will notice, those ones serving news without supporting amp are also in the tops of the search results.
