It's not like people are planning on using these in production. It's just some fun hobby projects that are useful for, say, online Python tutorials and stuff.
There's a fairly large class of scientific computing oriented apps where having a widely deployed and fast VM with CPython compatibility would be fantastic. Python (for better or worse) has a large library of open source computational libraries, but shipping an embedded CPython VM is a pain. As an example, I helped advise an undergrad working on a program to calculate collagen fiber orientation for biomedical research labs. Figuring out cxfreeze or other Python packaging systems took longer than writing the actual app.
Unfortunately JavaScript doesn't have broad scientific library support and grad students in non-CS fields don't always have the time to become versed enough in C/C++ to create a usable app. So CPython & associated C libraries ported to wasm could be quite useful... This could apply to R programs as well.
Re: grandparent, just because a project offends your sense of purity doesn't mean it isn't surprisingly valuable for others.
