Password Protect or Lock Features

Do you guys think that Locking or Password Protecting certainFeatures, Parameters or Items in the Feature manager would beuseful?

Example:

Sometimes I do initial design of a part and then pass it on to apeer, the base design id done but it needs more work, like fillets,chamfers, holes, reliefs...
The drafter needs Write access, but I'd be more confortable Icouldn't modify the based features (Happens a lot with sheetmetaldesigns).

I thinks this would also work great for Equations, Configurations,Custom Properties.

What do you guys think?SolidworksGeneral
