That's easy. Can you run spreadsheet programs, image editors, IDES, etc by default on consoles? Just approved software, no jailbreaks, hacks, etc.
I can’t run Xcode on my iPhone either even though that’s what I need to develop apps for my iPhone. Even more strangely I can’t run Xcode on the iPad Pro despite it literally running the same chip that runs Xcode on a cheaper device (the Mac Mini).
Yes, all of this is available via web browser.
Ah, nice, can I do any of that offline?
Well, you've asked if it's possible, not if it's practical and convenient under any circumstances.
I can't edit my comment. Console vendors don't envision consoles as general computing devices, which kind of tends to end any sparky comments one might make on the topic.
Apple also doesn’t envision that you can run arbitrary root code on an iPhone either
Given you can't run most games on current-gen consoles offline I'm not sure that's the point you think it is.
