What people are saying it is "fixed" with HotS?
It definitely isn't in the Beta right now (edit: Oh, it might actually be, I didn't see the Permanent flag before. Has anyone tested it? As far as I was aware it's just a method available to categorize Behaviors and reference these categories somewhere else. ), and I doubt they wait to add this specific feature at release. It's not even really a feature in my opinion. But I don't know of course.
If your system is data only I think there is a way to fire effects before the unit actually dies, that might work (instead of using Death Response it's something like Damage Response with Killing Blow checked. I don't know the exact names etc though, I'd have to search myself). If you also use triggers I would use Custom Values in your case and just save the amount of Terrazine every unit has through that. It is probably the easiest way to do it like this, but I don't know if there is a way to reference/access the Custom Value of a unit via Data, but most certainly not. So you'd have to make the whole Terrazine ability costs etc. via Triggers instead of Data.

Taintedwisp AuthorHello, I made a Buff System where a unit can spend terrazine gained from killing heroes to buy attribute points using an apply behavior and a stackable buff, now I learn and all units loose their buff on death, How do I keep the buffs, the permanent flag doesn't seem to work. People are saying this is fixed in HoTS, But I am planning to release the beta withing 1-2 weeks. on WoL :P
