I'm more interested in the reasons why it should be done at all.
Pruning does not prove the table is not in use or required. Imagine all your clients going down due to a simple logging-table that is only used once in the entire application, in a not-often used function.

After a debate about how it could be done and whether it should be done, I was struck by my colleague's statement of 'a lot of effort and potential pain, for not much gain'. There is of course the obvious risk of removing a table that really is used and causing a live system to fail.
..and what is the gain? That some empty unused table is no longer present? How much space did you reclaim with that action, and how much does space cost these days? Now compare the potential gain to the potential risc.

I would strongly recommend creating some documentation; that would slow the development-proces, but it would also result in a stronger grip on your datastore. Someone wrote a SQL/Linq/EF-statement? Please update the docs and jot down which tables are impacted and when.
