It's probably in keeping with the rectangular compression block for reinforced concrete... no sense in using a triangular block because as the outer edge of the base plate deflects, the load is reduced...

I was not aware that this had made it's way into the Design Guides at all. It is certainly possible that the method in the design guide is an improved upon version of the methods first introduced in the Drake / Elkin paper.

Back when I was young, I worried about the arbitrary use of triangular blocks when putting a baseplate against the concrete, considering that the plate could not be absolutely rigid and the column shape stiffened it differently. I satisfied myself by considering it as a cracked concrete section with the anchor bolt as the reinforcing. I then took the resulting force distribution and applied it to the baseplate. This allowed me to see that the triangular diagrams were reasonably conservative.
You might be able to do something similar with LRFD.
