Why do battle shounen mangaka blow their load so early?

[Papasmurf]

Requiem Stands bringing power creep into the system with how GER's existence creates a pretty noticeable plot hole in Part 6's conflict even getting the the point Pucci could come close to Heaven.

Part 5 is also coincidentally the only part you could actually skip and not miss a single thing.

But there are Giorno references in Stone Ocean

One single reference.

One single reference > Zero references, so it still adds something .

Even though Part 5 adds very little in terms of character relations within Part 6 beyond the idea that DIO had children, there are several important aspects to the world building in JoJo that means it can't be skipped, such as the origin of Stands/Stand Arrows as well as giving a more solid idea to how fate works in the series rather than just being a buzzword characters like to throw around (something that would be fairly integral in Part 6 when it comes to Pucci's goals).
