Transmissions and symptoms are roughly correlated through viral load.
The household attack rate of ultimately asymptomatic infections is much lower than ultimately symptomatic. The window for vaccinated people is also shorter since mRNA loads peak at about the same levels (where the entry criteria for the study was the same level of symptomology) but they decline faster and have less culturable, infectious virus for the same level of mRNA load.
And delta already spikes viral loads much, much higher in the presymptomatic phase of an infection (doesn't matter if its naive, breakthrough or reinfection) so that people are walking around spreading it before they know they have it. That ship already sailed.
Once someone is infected, then its better that they get less symptoms and less viral load / less shedding and that they're vaccinated.
