It's not technically needed, true. And like you say, I don't know if Busy.org would implement it from the get-go. I'll ask. Edit: According to ekitcho, it's not a big immediate priority, but they are counting on the change [as part of Busy's model].
In any case, this is one change that gives more potential to Steem as a platform sooner rather than later because there are front-ends in the works that would benefit and be incentivized by it.
No doubt, I think it's a great addition.
Agreed.
