There's a lot of WASM in GUID-named binary blobs though (most of those have one JS file and one WASM file included, some only a JS file).

Does three.js make heavy use of WASM and bundle them in blobs with GUID names?

PS: yes it appears to be three.js, looking at other three.js demos they also have those blobs with one JS and one WASM file in them. I'm surprised three.js uses so much WASM!
