I don't see it as any worse than having a list of items you require.
Nowadays I think it makes a lot of sense.
Very few folks are starting from scratch when they get married, even if they havn't lived together as a couple then normally at least one of them lives in their own home.
What use is two toasters let alone three or four.
The way I see it is, if your guests would take umbridge at you making a sensible request, then just maybe they shouldn't be on the guest list in the first place.
