Why disable household address management?

Hi everyone,

This may seem like a really open question, but I'm keen for some advice.  I've inherited an already set up org and they have the Household Address Management in NPSP settings DISABLED.  We don't have any documentation as to why we disabled the default setting.  I'm obviously investigating internally, but wondered if anyone on here might have ideas as to when the Address Management function isn't helpful and you would want it disabled.  Appreciate any wisdom or thoughts you might have!
