I want to create a Scratch 3.0 extension that adds local variables. Unfortunately, it seems like only a limited number of trusted extensions have access to the current stack frame, which I need to track which local variable scope to look in. Is there any way to figure out which one I'm in?

There already has some possible: Temporary Variables/Sharkpool's Temporary Variables/Turbowarp Temporary Variables
