But you have the same problems in C, even worse.

Because you need to emulate in C the features that more advanced languages have buitin, such as virtual tables, tagged union, lists, hash map, and whatnot. This is just a lot of conventions that are specific to each project that need to be learned and put in some style guide or development guide. In big projects, different developers will use different conventions in different part of the code, that's unavoidable.
