I'm arguing from RAW when I say that Wall of Fire persists for its duration unless something breaks the caster's concentration or ends the spell. I provided the citation of "Duration" earlier for that reason.

So yes, there are interpretations. If someone says "this is my interpretation" I'm okay with that. It's when someone says "this is RAW" and it's nowhere to be found in the RAW that I take issue.
It's both. The RAW is that Wall of Fire lasts until it ends. The interpretation is that that extends to environments that would be atypical for mundane fire.
