Yeah, Greyhawk's 1e quasi-deities (Daern, Murlynd, Keoghtom, Kelanaen, Tuerny, etc.) do not qualify as quasi-deities in 5e.I agree with all of what you posted, except that there is a minor correction here. Quasi-deities is the category, not a specific type.
"Quasi-deities fall into three subcategories: demigods, titans, and vestiges."
Edit: Nevermind. I see you were talking about how quasi-deities are used differently in other editions. Tired minds don't always get it early in the morning.
1e-4e titans are not titans in 5e.
Many demigods in 1e-3e are not demigods in 5e.
Many vestiges from the 3.5 Tome of Magic are not vestiges in 5e.
