The matrix_col_t type was added in commit 0284431ad9 (part of #3449), but then the code which used that type was removed in #6140, and no other users were added since that time. The presence of that type, however, limits MATRIX_ROWS to 32, which probably does not matter for a real keyboard, but prevents doing things like making a firmware to test all existing pins on a board like Teensy++ 2.0 (which has 46 GPIOs).
