Oh, yes, you're right. From Edge Guides:
Dynamic finders have been deprecated in Rails 4.0 and will be
removed in Rails 4.1.

I thought the other way around, that dynamic finders are better choice.
But the thing is that .find_by may return exactly a model object, but
.where returns ActiveRecord::Relation in all cases.
