In practice, (and yes, there are always exceptions to be found) BYOB is rarely used to any measurable benefit. The API is substantially more complex than default reads, requiring a separate reader type (ReadableStreamBYOBReader) and other specialized classes (e.g. ReadableStreamBYOBRequest), careful buffer lifecycle management, and understanding of ArrayBuffer detachment semantics. When you pass a buffer to a BYOB read, the buffer becomes detached – transferred to the stream – and you get back a different view over potentially different memory. This transfer-based model is error-prone and confusing:
for (const arr of arrays) { result.set(arr, offset); offset += arr.length; }

Let’s take a specific example, dismantling items at the forge. Players interact with the forge and choose individual pieces of gear to dismantle, converting them into a different resource called spirit dust.
