I didn't say that - I was giving as evidence the fact that moving things around at 640x512x4 was slow, and that 320x256x8 would be just as slow - same amount of data to move.

Yes but adding chunky modes in ECS or more likely a slightly tweaked ECS would still be possible.

Absolutely, but there was no call for a chunky mode back when the chipset was designed. The intention was to save memory where possible as most productivity screens use a low colour count, and gaming was very much a secondary part of the design, if it was even considered at all.

Still couldn't be as crappy as the [IBM][PC] VGA Mode-X where pixels are chunky distributed over 4 planes and the processor having direct access to one plane at a time. But we liked it!

Yes, there were indeed. Even more fun setting up interrupts for paging in/out memory for high resolution SVGA modes in DOS though
