Allocating array on heap using Box::new([;]) results in stack overflow

These aren't details your typical Rust programmer ever cares about. Embedded programmers are more likely to be aware of global_allocator and friends. FFI programmers need to be aware to not attempt to mix allocators. Even those groups usually don't care about how the compiler goes about lowering the source code to the system API (or beyond).

You run into global allocator replacements in WASM pretty often (which is sort of an embedded environment, I guess), and there's a few cases where the performance apparently mattered enough that I've seen apps use mimalloc or the like, you could stretch "typical Rust programmer" to those I suppose.
