@pvillard31 @mattyb149 Reviewed it and the changes look fine, but noticed
something weird when I fired up a full build w/ it. When I'd add one of these
tasks, the status would stay spinning at "validating..." until I hit start. Did
either of you see that? Didn't seem to actually break anything yet.---
