Sufficient, probably. But more detail is always nice in a tool.
If we assume that the size of the book can't be bigger then pages devoted to that would mean fewer monsters.
I didn't use the pages from the 2014 DMG and I wouldn't use them now so I'm happy they're not in it.
It is far easier for me to take in all the monsters and then use those for inspiration on how I want a new one to function and then find a monster that is the CR I want and use similar numbers.
