 I propose to implement this in the basic WordPress functions so that they
 can be simply activated or not activated (with checkboxes in the settings
 section):

 Intersection Observer API
 Mutation Observer API
 Speculative Loading (integrate the functionality of this plugin into the
 basic system – https://wordpress.org/plugins/speculation-rules/)
 PWA – (integrate the functionality of this plugin into the basic system –
 https://wordpress.org/plugins/pwa/)
 Use CSS content-visibility in standard WordPress themes

 PS. This will allow us to use fewer plugins and your own code, speed up
 site loading, improve security
