Not at all, which wasn't my point at all.

However, having an abstract if you are going to present lots of information is definitely always good style. The scientific community require them on all papers - to help people decide if they should bother spending time to dig into the material or not. Not to make the material accessible for grandmothers.

That is exactly what a good tl;dr provides.

EDIT: Fix borked sentence.
