I'm a belt and suspenders kind of gal when it comes to my pets. They're all microchipped and they're all tattooed.
The way that microchipping might deter theft is if any show or displayed let it be known that some/all of their quilts were microchipped. It won't stop a determined thief but it may well deter an opportunistic thief who may fear being caught.
The person who mentioned using it to trace the history of a quilt had an interesting idea as well. Even if all you know is the list of owners, that's pretty fascinating 100 or 150 years down the line.
