Using a new option or a new wake lock both seem fine to me. The wake
lock state "locked-background"[1] can be used for that. But note that
the currrent draft w3c wake-lock spec requires the document to be
visible[2] to use wake lock. If the draft spec is implemented at some
point, it will look like[3]
partial interface Geolocation {
attribute boolean keepAwake;
}
which is not very different from a new option, IMO.
