You can even add all the possible IPs to the list, then they will have
all the same priority, and just during a DoS attack

Do you know that will happen when a dev will add other IP to this list? Someone will see it because ... it's an open source project!
Do you check every day what devs add to the Bitcoin Core?
Again, it isn't a black list, it is a "low priority list", that enable it self only
IF there is a DoS attack.
So, because of this, it's better to put all the Bitcoin network in a trash can a let the market go somewhere else

If you don't like this list, fork it, it is just a click on the github repository.
I have no idea what would be the effect on the network if a portion of the network did not use the default and used -disableipprio instead.
It will be as the Bitcoin Core works now. Someone thinks that nodes now are easy target for DoS attack.
You think not, then, better for yourself.
