Comment (by mor10):

 These examples of custom- and anti-patterns are precisely why we need this
 implemented in core asap: Lazy-loading is becoming more and more well-
 known by site owners, and they are turning to plugins to get it done.
 Rolling out a cohesive method with a proper developer interface in core
 allows plugin developers to upgrade (or sunset) their solutions in a
 graceful way.

 I am wary of any attempt at modifying the spec to conform to plugin
 behavior. A better solution from my perspective would be to notify all
 plugins which offer lazy-loading functionality of the upcoming change to
 core and give them time to test and update their solutions to fit.
