>There's no namespacing feature provided so you're left with the convention of picking a few letters as a prefix and hoping it doesn't overlap and yet is succinct enough to not be annoying.

I've been using C on a daily basis for 30+ years and name collisions has just never been a problem.

Granted, it might be due to lack of a package manager so micro dependencies ala import is_even is not a thing here, but still, in practice, no name collions occurs.
