Why not a have the .text property contain a Blob URL? Metadata tracks can contain significantly large pieces of data.  Exposing the data as a Blob URL allows UAs to only extract the cue data from the media stream when that data is explicitly asked for, rather than extracting that data proactively, whether it will be used or not.
