What is the rationale behind having a Decoration.ocd folder?

From my understanding, packs can be used to sort definitions so not every scenario has to load every definition. But decoration is something almost every scenario will have, so pretty much every scenario should activate these objects.

If you really feel we should start sorting objects already (which I doubt - the engine loads fast enough in my opinion), I think it would make more sense to sort out melee (weapons) and settlement (production buildings and processed materials) from the rest.

The current approach will only discourage authors users from using decoration because they have to activate an extra pack. I think this is a bad idea.
