The STL is a weird mix of brilliant, visionary API design and abject failure.

Sounds like most software projects. IIRC the Scala folks have pretty much rewritten their entire collections library twice already, and that's with the benefit of hindsight.

I'd like to see a mature new language in this space with a good ecosystem too but the number of major swerves they've taken in the Rust design already makes me inclined to think that, like C++, they're going to discover they made some serious mistakes along the way.

I see what you mean but I do think the STL was more visionary, and more abject, than almost anything else in its reference class. Truly unified sequence operations, for example, were novel back then. On the other hand, binary search _wasn't_; I'd love to know what that guy thought he was doing.
