There are about 20k header files, none of them has #pragma once. Updating that will bring many unnesessry git commits. I doubt that one more define in preprocessor tables is a problem we should fix. The LOC argument also does not sound very convincing. The include protection is at the top of the file, not mixed among other code. Replacing 2-3 lines with one will be barely noticeable.
