Initial bite is irrelevant to the point being made.
The range of motion of the disc caliper is very small compared to a rim brake as are the range of motion of the levers themselves. This is what causes me to feel a lack of modulation, it takes very little movement on the disc brake lever to generate a lot of force. I only have 1200 miles on them, so, I am still learning but it is not comfortable yet
Are you trying to say that rim brake levers have more total travel than disc brake levers? Both are limited by reach and bar clearance so I would think they have roughly the same total travel. The real difference is that disc brakes produce a higher maximum braking force, which you can only utilise in high speed braking as demonstrated in the video. So of course you are using less of the travel when braking normally. Unfortunately you can't have it both ways unless you had a non-linear lever travel to force relationship i.e. rising rate.
I know you think the bite point is irrelevant, but you will find in practice that it helps a little if you are finding the brakes too grabby. Have you actually tried adjusting it? Think about the bite point with rim brakes, which you have been using for all these years. How much does the brake lever move before your brake blocks touch the rims? Is it more or less "dead" travel than what you have now on your disc brakes?
