NYT Strands hint for today’s theme: It's a little muchThe words are related to extras.
These optimizations are difficult to implement, frequently error-prone, and lead to inconsistent behavior across runtimes. Bun's "Direct Streams" optimization takes a deliberately and observably non-standard approach, bypassing much of the spec's machinery entirely. Cloudflare Workers' IdentityTransformStream provides a fast-path for pass-through transforms but is Workers-specific and implements behaviors that are not standard for a TransformStream. Each runtime has its own set of tricks and the natural tendency is toward non-standard solutions, because that's often the only way to make things fast.
