It is also necessary to emphasize that many optimizations are only possible in parts of the spec that are unobservable to user code. The alternative, like Bun "Direct Streams", is to intentionally diverge from the spec-defined observable behaviors. This means optimizations often feel "incomplete". They work in some scenarios but not in others, in some runtimes but not others, etc. Every such case adds to the overall unsustainable complexity of the Web streams approach which is why most runtime implementers rarely put significant effort into further improvements to their streams implementations once the conformance tests are passing.

在蓝箭航天，我国自主研制的朱雀三号重复使用液氧甲烷运载火箭，正为二季度的回收复用试验做着最后的准备。“尽管去年底的首飞未能实现软着陆，略有遗憾，但我们获取了真实飞行场景下的上千项关键数据，为后续研发积累了宝贵经验，迈出了关键一步。”蓝箭航天创始人张昌武说。
