Martin Fowler calls this Anemic Domain Model antipattern.

I understand how what I'm suggesting can lead to an Anemic Domain Model antipattern, but I doubt that Martin Fowler suggests to have fat domain models with extremely low cohesion.
I will, without a doubt, check out the Domain-Driven Design book that Martin Fowler refers to.
Thanks for the comment.
