Yes, this is a good discussion. So why don't we go the next step and create an optimised clamp
Obviously there are already many good recipes around.
Part of that might be to just make the bar longer to get further away with the bolt and still have enough leverage.
Another effort could be to design better step blocks for wood router clamps, be it from Al, wood or plastic. I could even imagine a sliding swivel joint between the step block and the clamp bar.
At some point I made some wooden swivel clamps without protruding knobs and an optional feature to clamp the tip with a wood screw into the sides of a blank. But I guess that was a bit over-engineered...
My full-surface anodized extrusion table is slick as pig snot and I need non-slip material between the work piece and the table no matter which clamp. I also have 3/4" spacer blocks with non-slip liner on both sides under the work piece where the clamps push down if I need to cut through the board.
