Feature description

When the AMP boilerplate is removed by the SSR logic, preloading of the AMP runtime is less critical and it seems to slow down other assets that are of higher priority in that scenario.

The Optimizer should remove an existing preload for the AMP runtime again when the boilerplate was indeed removed.

This was originally reported by @mehigh for an XWP project.
