Dimensions should dangle but don't, why I'm disillusioned with SolidWorks

When replacing the model in drawing, certain dimensions should dangle as they are no longer attached to anything in the model, but they don't. This could cause serious errors in production if the dimensions weren't as obvious as in this case. Note the table should also fail as it too has changed in the model.

I reported this bug to my VAR, he pushed it to SolidWorks. SolidWorks state that it's working as intended. I can't believe anybody could believe this is working as intended. I broke my own rule about wasting time reporting bugs.
