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.

Implementations have had to develop their own strategies for dealing with this. Firefox initially used a linked-list approach that led to O(n) memory growth proportional to the consumption rate difference. In Cloudflare Workers, we opted to implement a shared buffer model where backpressure is signaled by the slowest consumer rather than the fastest.
