The thing is, even with the raw pointer the hard part is resolving ownership questions, not resolving the type. The tricky questions in C are: am I responsible for freeing it or is the library? If I send it into this function call am I transferring ownership? Type deffing doesn't make any of that easier or harder to figure out. Whether the thing is a handle or a pointer doesn't really complicate things, if that makes sense.
I get what you're saying, but I'm speculating what not type defing might help with. It's clearly advice that drifts around. Even if you think it doesn't help much it must address something for somebody, right?
