I know, but the problem is that the design spec could be specific or vague based on the company, the clients of most software companies usually do not have too many experienced software engineers(they do it themselves if they had), so most of the design specs turn out to be wordy pieces of bs totally meant for the management.

Not in the places that I have worked. I am use to seeing very good highly technical documents. The audience is always the engineering software group. Management only cares that it was done, they hardly ever actually read it.
