"Native" types like usize and isize as used in Rust I'm totally fine with.
What I got frustrated with in C/C++ is the insanity of each and every third-party library redefining every type. I understand the history and reasoning behind this, but it's one of those things that ought to have been fixed in the early 2000s, not decades later when it's too late.
I think by C++17 (14 even), it was in a very good state and since then, third party libraries are better and better. So really, a decade and a half later than you think it should have been.
