In addition to two versions of the same method, similar but not identical, the documentation for the ActionView::Helpers method link_to states that link_to accepts the same options …
This is the reason we don't need to eager load something like ActionController::Base . Because Rails already eager loads your models, controllers, etc and if you are actually using Action Controller, you will have a controller inheriting from ActionController::Base which then forces it to be loaded on boot.
Similar reasoning applies to most of Active Model modules. There is no need to eager load ActiveModel::Validations because if an application is using it, it will load a …

To make the improvement of notifications and log subscribers more visible, here's the code that did the same in2.3. You decide which you like better. I certainly enjoy the decoupled-ness …
…both Giles Bowkett and Matt Aimonetti. Both of them painted building ActionController::Metal applications as some sort of byzantine, impossible task which can only be accomplished by a Rails core member.
The bit in bold is false. My position was and is that ActionController::Metal is awesome and powerful, but irrelevant to what most users need, and miles away from the cutting edge. And I never even mentioned Metal in the post specifically; it just fits into my general position that …
