https://www.chromium.org/blink/launching-features/#new-featu... shows the process followed. Creating an explainer comes first, which is to be presented immediately to an incubation venue like WICG. Prototype behind a feature flag. Then widening review further, getting request for positions. It's recommended to start an origin trial which will run for a quarter or more. If everything is going fine, then one can start the intent to ship process.
Looking at https://groups.google.com/a/chromium.org/g/blink-dev paints such a picture of slow, controlled evolution. It's absurd to me this kind of flak blasted in the air trying to shoot down something that is generally so measured & controlled & steady in releasing. No one else has anything half this controlled. Who else does Intent to Experiment or Intent to Prototype? Few software has such a model where it's so clear what's coming, what's happening, where change & evolution is done in a controlled, slow, deliberate fashion, where prototypes are worked on & tested in the field for a significant amount of time before coming back to shipping. Few other softwares have such an extreme responsibility in going to working bodies, in soliciting requests for positions, where all manners of discovery are done.

Unclear what specific specs you are trying to throw under the bus here. PWAs took a long time to cook, in my view; hardly did they seem rashly done. A lot of people are really offended the web has MIDI & Gyrometer & other support, to the degree that they wouldn't let others enjoy this.
