The docs say:
"A unique identifier for the store at the given URL. It must be
uniquely and reproducibly derivable, such that multiple instances of your store
return the same UUID”
My reading is that the store UUID would be unique to a specific database since
it is only unique to the URL location of the store. I thin the docs use
“instance” in a strictly OOP sense.
