Another one in favor of having an open area in the corner. I use a drawer jig, sort of like the right angle one you show but larger, and it tends to get build up in the corner. I keep cleaning it out with a chisel, but I plan to rebuild it with a relief area. I also plan to use formica on the base, so glue will come right off. Melamine will work for a while, but eventually dried glue will make the coating pop off in spots...I have a whole workbench top that has done that.
Glen, thanks for the idea about the forstner bit in the corner. I will do that today.
