A lot of us have done that. Also, one time a friend broke his chain on a ride and I fixed it with my mini tool. Except I missed the front derailleur. I had a lot of trouble connecting the chain so I didn't want to break and reconnect it again so I took the derailleur apart. It would probably have been easier to just open the chain.
