From a player's standpoint I like to be able to see and use all of the old, as well as the new.
From a tesing standpoint, it is a lot nicer to have the option to balance test a mod against all the origional items - the comparison helps prevent the creation of super-deity mods.
Few things irritate me more than trying a mod that looks gorgeous and well put together instantly outclass everything else in the game. I'm sure every one of us have been tempted, but being the baddest boy on the block provideds no challenge, and loss of interest.
