Well, they've never put out a book on how to run combat or how to handle social interactions. Why would they do a book on exploration?
I think this is one of those things a video series would be better, but honestly even then I'm not sure anyone could do it justice. There are so many different styles, your best bet is likely just finding a podcast or stream you enjoy and try to get ideas from there. I could explain how I handle a lot of things, but it may not work for anyone else. Maybe a separate thread of suggestions?
D&D gives you the tools, the DM and players have always been responsible for figuring out how to use those tools. The answer may well vary from table to table.
I was thinking of Into the Unknown from 4e and Dungeonscape from 3.5e and how both cover aspects of exploration specific to dungeons. A separate thread with potential suggestions for different styles of play sounds like it could be really useful.
