Good work on rewritting the logic to a slimmer state.
Wouldn't be it more readable if you turn lines 407-422 into a boolean
function which would return true if "supportsStorageSystemSnapshots". Snap this
chunk of code could prove useful on creating unit tests and documentation as
this segment clearly aims to check this condition solely.
