M because of caMel, like we have N because of kNight. In his upcoming book Jean-Louis indeed uses M and G for Camel and Eagle, in all his variants.
In variants as large as Terachess or Chu Shogi having 1-letter piece ID becomes a real challenge. For Tenjiku Shogi it becomes impossible. WinBoard uses 'dressed letters', like P' or P". Unlike 2-letter IDs this can also be used in FEN.
