I can see how the 4e ecology of the Succubus article informed the 5e succubus, although there seem key differences.
Angels aren't reference, but its only a single page vs. an article and 4e angels haven't made an appearance in 5e, yet.
Succubi detached from devils can now breed and it appears to be the primary was they reproduce vs. evil souls like most other fiends, so that's a big difference because it frees them more from the lower planes then other fiends.
Of course they can now be found on all lower planes in service to all manner of evil, but your 4e article was inching in that direction anyways.
The succubus companion isn't present, but its not hard to update the idea to your 5e succubi.
And redeemed succubi are even easier to do in 5e, a Good Aligned being raises a baby succubi.
The Abyssal Incubus, which thematically seemed influenced by the 3e incubus, aka not just male vs. Female, but violent rapists, vs seducers. This doesn't appear apparent in the 5e succubus and there is no beast shapes.
Dispite not being the most powerful fiends, the breeding means they can invade any realms and grow in numbers in time, which in one way makes them the scarest of fiends who depend more on damned souls to build thier numbers up.
One thing I wasn't as big on, its the whole undertone of chaste=good, lust=evil, which is an outdated ideal of morality. I'd have made the Angels of Love more free love hippy idealists, prosex angels instead of love as chaste and asexual. I do get you were just following the traditional moral paradigm.
And the art in the 4e article was good too.
