> So, why do you suppose this is?

this is my personal assumption, observing the golden rule like the other commentor mentioned, this most likely isn't something nefarious but most likely a low priority that they will work at a later. They're busy trying to keep the spotlight in this cutthroat hype cycle and I think it's safe to assume they're busy pushing new models like we saw gpt-4o than low hanging fruit QoL features that might even risk breaking things. You mention how they "flat-out" refuse to answer the question but I think it's reasonable to think that after yesterday's announcement they're swamped with messages to focus on this right now.
