When a host runtime provides a byte-oriented ReadableStream from the runtime itself, for instance, as the body of a fetch Response, it is often far easier for the runtime itself to provide an optimized implementation of BYOB reads, but those still need to be capable of handling both default and BYOB reading patterns and that requirement brings with it a fair amount of complexity.
The semantics around releasing locks with pending reads were also unclear for years. If you called read() but didn't await it, then called releaseLock(), what happened? The spec was recently clarified to cancel pending reads on lock release – but implementations varied, and code that relied on the previous unspecified behavior can break.
