sunfish added a comment.

Wasm gives users reasons to want -mthread-model single that other architectures \
don't, even when -matomics is enabled by default.

When shared memory is used, wasm requires modules to declare a max memory size, which \
is a burden on applications that want to use dynamic amounts of memory. Wasm is more \
sensitive to code size than most other architectures. And, interoperating with \
single-threaded JS is easier from single-threaded wasm (JS has access to \
SharedArrayBuffer and atomics, but not all JS wants to use that).
