Both. As @Edgar Ironpelt states, there might be some important to the formation of the world (such as in my "Dragons Must Die" campaign), or may come as custom creations borne out of play or just wanting something that fits the world (Like the Maughtley - dwarves who became minotaurs due to...
Just went and played with it - I definitely like the looks of it. Also, so glad it has a dark mode off the bat!
If you don't mind, a few screen shots from a test character (using 2014 rules)...
I watched an in-depth unboxing that even went over the contents of the module (include differences with the original). You could scrap the premades and character "placemats" and it would still work - it would just then have components that I'd wished I had back in 198X with battlemats and...

This is an example maneuver...
A mix, and a lot of cases of published world with modified adventures, or homebrew world with published adventures.
I use published worlds on occasion because some people are more familiar with those worlds, and for a while I was a bit ashamed how "kitchen sink" my homebrew world was. But...
