Maybe this list needs some explanation.

List of recent VLOC incidents:
Vale Beijing sustains structural damage during loading in 2011
Stellar Daisy foundered with all hands in 2017
Stellar Unicorn finds structural damage in 2017 and later sold for scrap
Stellar Queen sustains cracks on main deck in 2017 while sailing in ballast
Stellar Cosmo sustains structural damage while searching for survivors of the Stellar Daisy and later sold for scrap in 2017
Stellar Banner strikes bottom and later declared total constructive loss in 2020
First, let's remove "Vale Beijing" and "Stellar Banner", as they clearly don't belong with the rest.
Both "Vale Beijing" and "Stellar Banner" were (are) purpose built VLOC vessels, while the rest were crude oil tanker conversions.
"Stellar Unicorn" (ex-Musashi Spirit), built in 1993 and converted to ore carrier in 2009.
"Stellar Daisy" (ex-Sunrise III), 1993/2008. Also, she did not "founder with all hands", as there were 2 survivors.
"Stellar Queen" (ex-Hydra Star), 1994/2010.
"Stellar Cosmo" (ex-Suzuka), 1992/2008.
I think I will not be too far off when I say that they were pushed to their limits by their owners, to try to squeeze the last dime from their service.
The reasons why "Vale Beijing" almost foundered during her first loading... will maybe be published one day.
As for a VLOC (or any other ship type, for that matter) to sustain irreparable damage after grounding, this is nothing new, and may well be completely unconnected to her design characteristics.
"Valle Beijing" incident did prompt many actions (and the vessel and her sisters continue to trade to this very day), but there was no word of VLOC design review in general after the grounding of "Stellar Banner".
