I honestly only got a USB-C hub because the laptop didn’t have an HDMI port, so if we count the USB-C hub, the HDMI port is the most used port on both my work and home laptops. If we ignore the USB-C hub, it’s second only to the USB-A port, which my kids use for a mouse to play Minecraft (I rarely use it personally).
You’re right, it’s not my call, which is why this is a Meta post for community discussion, which will ultimately require buy-in from the mods (i.e. those who would enforce such rules). I’m providing my $0.02 to the discussion.
