Your original comment sure didn't do that. It just gave an incorrect answer.
What exactly was "incorrect" about it? He asked for a purpose and a use-case not an explanation.
> not an explanation
Wrong.
.... It's literally right there:
> I'm still clueless on what the purpose and use-case is for ReBAR
Are you seriously debating this?
They wanted a basic explanation in response to that.
Or to put it differently, I would take the sentence "He asked for a purpose and a use-case not an explanation." and replace the word "not" with a comma.
I quoted the direct response. I have no idea what you're debating.
I'm not sure how to put it simpler.
I agree with "He asked for a purpose and a use-case". (This is what your quote supports.)
I disagree with "not an explanation".
When asking for a purpose and use case, they were asking for an explanation.
