I have seen the string method advocated by some on rare occasions. Same for verifying other aspects of the chassis such as squareness.
I think a lot of people love gadgets and trust anything hi tech as being superior.
That said I have no intention of ever again attempting to drive a kart I have not verified the chassis on. I am tired of being the guy with the yellow karting shoes!
I am currently trying to set up our shop to be able to do some chassis checks on a regular a basis.
