I tried it and have had no problems with it so far. The kerf compensation is just fantastic. After carefully measuring the kerf in my material using the kerf measuring jig I made a new laser cutting tool in my user library, did the tool-path thing and ran post. The results were spot on – all the dimensions were exactly per the design.
Thanks very much for this Gareth! (Looking forward to seeing it get built into in Fusion 360.)
