I like them (in Rails) even though they add such little functionality. It's more about the concept of moving code from your models and controllers into separate files that contain a functionality in its entirety. Make those models small again :)
I see! Definitely agree on slimming down. My company's go-to for slimming down model is always Service Objects, so that's what I've been used to.
I think one of these days I should definitely try out concerns! Thanks for sharing :)
Serivce Objects and PORO is a must when you write a rake tasks. Processing the input and passing it to the service is all my rake tasks do. Much easier to test.
