An advantage of WASI is that it mostly works on non-WASI runtimes too, as it can be compiled to one or more normal modules (with the multi memory feature).
So a possible reason is that maybe they are not interested in offering general interfaces but just a single python specific one.
In this case they could have likely used wasi for that too but I can see how it could have been seen as an overhead
