That's usually with reference to code that might then load them again,
such as another library. Without specifics it's hard to say.

If these tools depend on the C code terminating cleanly to operate
correctly then they'll also break if the OS crashes, the system loses
power, etc.

Exiting a program without calling cleanup is in many ways just a
particularly friendly kind of crash, and it's often actually much more
efficient than doing cleanup. Why neatly tidy the floor when you're
about to demolish the house? Total waste of time.
