> Devices should be truthful in the type of content they request.
I think that websites should assume that devices are being truthful. I should be able to request the desktop view on my phone or request the mobile view on my computer. The former I can do sometimes, the latter I can only do with developer tools (and usually doesn't work because the website detects that I'm on desktop!). Browsers could add a header to switch to the mode in which the website dynamically readjusts based on actual device parameters like window size, but by default I need the view to be what I requested regardless of my window size and device type.
You know how Wikipedia has no table of contents on mobile? I made my browser request the desktop site by default so that I could see the table of contents and don't have to tap to open the article sections. (Unfortunately, Wikipedia changed its desktop view UI by moving the table of contents into a hamburger button. On mobile the desktop view forces me to tap the hamburger button to view a blocking popout of the table of contents, while on desktop the contents are automatically opened in a sidebar.) If Wikipedia had forced a dynamic design on me to restrict me to the mobile view on mobile, then I would've wasted time opening article sections to decide whether I wanted to open them in the first place.
