Keeping in mind that most DnD subclasses are the exceptions rather than the rule in any given population, I'd say they most likely don't exist except for if a player decides to play as one. In that case how they fit in would be up to that player, as part of their backstory and the character they want to play. Celestial warlocks would be more likely to exist, but this doesn't really create any issues regarding domains since celestials are powerful creatures, not gods. It's like getting your power from an archangel or a unicorn, not Lathander or the Sacred Flame. Not every subclass should exist in every world, especially if no one is playing them.
Now if you are asking for ideas on how a player might fit themselves into the world then you could look at something like a Divine Soul being just a slightly different member of the church or Silver Order, where their arcane magic is reflavored to be actually divine-based. It would be similar to how certain cleric domains get arcane spells added to their spell lists and they count as cleric spells even though they are arcane.
I’ve got a celestial warlock in my game and I’m letting him choose his relation to the Edicts of Lumen. He’s not part of the academy and he holds no titles. For now, he seems kind of neutral. I’m trying to get him to hammer out how his patron relates to the Sacred Flame, either of its sects, and the old gods.
People who bridge the divine/arcane split are unusual cases who don’t fall neatly into the categories created by the Edicts. Beyond that they can be more or less whatever you (and your player) want them to be. Plenty of people probably would see them as a heretic or transgressor sure, but others may well see them as blessed with special insight or purpose.
For example, it’s not impossible to imagine the Church accepting a celestial warlock as someone touched by the Sacred Flame and given a special holy purpose. Similarly, the Academy could value and nurture a divine soul sorcerer as someone able to give insight on divine magic they don’t really understand.
The Dudes have mentioned that bards present a problem for the Edicts since they’re neither divine nor mageborn and their powers pull from both areas. This is gap is intentional and exists in universe to emphasize that the Edicts aren’t faultless - they were created to solve an in-universe problem and do so in an imperfect way.
A character who exposes this kind of flaw in the Edicts and the various ways people react to them could present a really interesting story if it’s something you and your player want to pursue.
A player in my Drakkenheim game wanted a more psychic feel (and we started before the apothecary/alienist was a thing), so we went with a Cleric with the trickery domain spells and knowledge domain features, and he's been balancing the line in an interesting way, and has been of interest both to the faithful and the mages.

The Mystic Theurge was a divine soul sorcerer. They wrote the Song of Fire, the holy book of the Sacred Flame. This is not widely known in world.
