General Why'd iCloud Drive and Documents & Data coexist?

[LordQ]

I came across this image which shows iCloud Drive and Documents and Data available to toggle on or off under iCloud settings.

My question is, isn't iCloud Drive supposed to replace Documents and Data? Or with one on the other is off? Or do both options share the same data?

I'm quite confused. Thanks in advance to whoever responds!

iCloud Drive is a replacement for iCloud Documents and Data.

Drive is not enabled in that screenshot, but Documents and Data is.
When Drive is enabled, Documents and Data automatically gets disabled, but all data is preserved.
