I hope to one day know enough about the Hive protocol and the code to be able to argue that.
On a note, I never found the 1 minute slow. I am afraid of the attack vectors and the consequences for layer 2 apps, but also excited for "needless extra speed" (I mean, exchanges themselves might take more than 1 minute to add the funds, even if the irreversability is instantaneous, because of their cronjobs)
I'd normally agree but every time I send Hive out to an exchange they usually credit me right after the block becomes irreversible.
