I am glad you have improved your numbering scheme. You know my view and I do not know your company enough so you are the expert now
I am sure you will test it and get it approved against various scenarios agreed with your business.
One thing is to me PDM/PLM is a business matter, so any decision that can affect others (ie information that needs to be communicated) should be made in consideration of the company and not a department.
Best regards
