When you boil things down, what's the difference between a Dragon wanting to build a lair and protect himself magically... and any other highly intelligent creature found in the MM.
The DMG should have the "Lair living, mastermind NPC building tools" that can be applied to any number of creatures that you might find this useful with.
Right now we are just looking at the Dragon because it's the one entry that is losing it's spellcasting. But if we apply the concepts of the Dragon defending itself... what happens when we move over to things like Illithids, or Beholders, or any number of other potentially world shaking "creatures" that need a lot of magic to stay that way.
I'd rather not have a lot of repeating text in the MM that could be better moved to a single location in the DMG. It also makes more sense located there in a "world building" way.
Going by the Fire Archons description, ecology and other background info, these things aren't going to be written completely out of the MM, so as for making your NPC Mastermind "Dragon-Flavoured", I'm sure we'll still be getting a lot of material to inspire us on the fly as well.
