I thought thin would not be rigid enough as well. I found that as long as the base of the sled can hold the runner and the fence at 90 degrees it's accurate. Thinner sheet stock will flex more but conform to the flat machine surface easier. If a thicker sled gets bowed you must press down harder to flatten it.
My 1/8" sled has a slight bow to it that's consistent, so holding the stock down as you cut it makes the sled flat. It's very lightweight with a single UHMW runner. It can crosscut 38" accurately with only 1/8" for the offcut to drop. It's this design, but no sawhorse. I have a workbench support :
