Official stance on AHK scripts.

You said it yourself. The developers support them then they are authorized and the TOS says do not use "unauthorized" software.
And you don't have to hijack anything to bot. Botting is botting as long as you automate something, whether you crack an app or inject code in the process memory.
But if you feel slightly dirty inside for leaving your char there crafting for hours and hours (or w/e you wanna do) using autohotkeys, I think you don't need anyone telling you that it's botting.
I'm not here to stop you, mostly because I haven't the power to, botters are sadly in any online game and even offlines (why they even "play" the game?).
You wanna use it, do it, but if you want my opinion for what it counts, it's cheating.
