Safe to delete built-in Smart Folders?

I have no use for the Unfiled and Untagged Smart Folders. If I delete those plists from the Smart Folder directory, will it break anything?
Thanks.

No, but I think they will probably come back. I’m planning to add a way to hide them. In the meantime, another option would be to put them inside a collapsed folder.

Tolerable workaround. Thanks.
