You usually don't want your code logic to stray from the mental or domain model of business stakeholders. Usually when my code makes assumptions to unify things or make elegant hierarchies, I find myself in a very bad place when stakeholders later make decisions that flip everything and make all my assumptions in the code base structure fall apart.
