Really glad you like it!
I’m not going to be including this in the printed version of the game - or at least not the printed version that I give out for free - purely because it would make the book too big for saddle stitching. I’d need to move to a perfect bound book and that becomes too expensive for me to print with the intention of handing them out.
My plan, and something I’m currently working on, is to put out a book of these procedures alongside a worked example demonstrating how to use them and a handful of ready-to-run dungeons generated using them. That will be out in print in the same format as the base game, but it won’t be something that I give out for free. At the same time I’ll be reprinting the base game and as with The Moss Mother’s Maze, people who pick up the dungeon supplement (and the treasure one, when that’s ready) will also get a copy of the game with it. Hopefully this makes sense!
