This doesn't change the fact that the PDF contains a ~440 word abstract. It comes off as a defensive marketing pitch when it's this long.

You're truly judging the book by its cover, but I have to give credit where it's due the abstract is very long.

It’s a clear signal the paper is gonna be hard to read. It takes a ton of work to compress complex ideas down to 8 pages for a conference paper. But that work makes it easier to understand. This paper did not do that work. In fact it seems they did the opposite: try to write a LONG paper as if that shows how much originality they have.

While it's less than ideal it's also a very useful (and pretty accurate) heuristic to weed out papers in an area where it is impossible to read all (or even most) of them
