I think the suggestion is just to use the view for maintaining these lookup tables. In this way one screen in the app could be used to maintain all of them but all queries (lookups) would use the individual tables and not the view.

So you get the best of both worlds. Optimal lookups and an easy way to maintain them. Add a new lookup table; no problem just add it to the view and it can be maintained through the same maintenance screen.
