You're right David, I doubt they used these terms.
I bet these came into being with Jazz teachers like David Baker, etc. needing an organizational method to teach improvising.
Chord tones are for me the best way to think when soloing, but
knowledge of various scales that go with each chord doesn't hurt my playing. I feel it gives me various "colors" I can draw from at any time. While I'm not a great jazz player by any means, I feel like any note is available to me at any time due to my study of scales, chords, transcriptions, etc. It's up to me to make it work out. As you hear from my sound posts here, it is with varying degrees of success.
