I think it makes sense to define a “stable core set” for #rails. The parts, where it is highly unlikely for DHH to fuck it up (due to the business interests of Microsoft and Shopify):
* Railties/ActionPack/ActionView
* ActiveRecord
* ActiveJob
* ActionMailer

Avoid ActionCable, ActionMailbox, ActionText, ActiveStorage, Hotwire. I’m not sure what to recommend regarding asset pipeline yet…
I think in the The Rails 8 Way, they will all be replaced with alternative gems…
