I turned this feature on months ago to see if it aligned with how we handle our B2B accounts (companies) in HubSpot. Without any customizable features it did not work.
That being said, I reached out to HubSpot service and was informed that once it is turned on you cannot turn the feature off.
This should have had a Beta view like the other changed HubSpot roles out. And please build an abilty to turn this off!
