Options are good but… in general I get very nervous deleting files.
So in this case I want an extra layer of protection against deleting files by mistake.
An option that will send files deleted from the pool trash directly to the Windows recycle bin. That way it will give me “one more chance” before a final delete. That would be the default action that a user could opt out of.
IMO… to me it’s weird that CB does not already use the system recycle bin to begin with. 
I suggested this same thing “way back” in the CB 7 days. Maybe worth another post for CB 8… I’ll think about that.
