Still, FR as the kitchen-sink flagship setting has to make use of and normalize all the material that's in the PHB. That's basically been it's purpose as a setting for the past couple decades. Everything has to have some niche and be worked-in and accounted for within the Realms. So I'd expect some reason why Ardlings are suddenly everywhere in FR in the next ed. I do think they're more appropriate to Planescape than FR, but those settings are both gateways that kinda work in tandem. They'll probably do something similar to what they already did with the Tiefs - like heaven crashes to earth somewhere and we've got heavenly refugees to go along with the devilish ones we've been meeting now in BG3. It works for me I suppose. FR is already a pretty high-magic high-fantasy setting.
Wizards of the Coast should create a new setting for the freak races (a place that "furries" can salivate over) and let The Forgotten Realms return back to normal. There are folks who just can't get it through their heads that having every inn, tavern and hole-in-the-wall resemble the Mos Eisley cantina quickly diminishes the uniqueness of anything beyond the classic "core" races/species.
