While somewhat useful - there are no systematic ablation and comparison studies, datasets, and quantitative evals here.
It's all anecdotal, so should probably be a blogpost and not a "paper"
"systematic ablation" - https://stats.stackexchange.com/questions/380040/what-is-an-.... How do you ablate a black box? You work with the inputs. I agree that this article lacks rigor, but I don't mind some structured thinking about what seems to work. I don't think the authors over-promised here.
I think of this paper as being in the same category as the GoF Design Patterns book.
