Depends on how well supported those stacks are. WASM is very well supported and likely to be getting tested/used/improved extensively as the years go.

I'd rather work on software that depends on three different tech stacks that are well understood and used by many, than software that depends on a single niche tech stack.

I'm not a "stick to a single stack for everything" kind of person, but here we're comparing Go or Rust, to Go + Rust + WASM. The first option is strictly and substantially less risky in this dimension.
