I think there are a few reasons why we should not do this:

- this attribute has always been about saving power, not about
accuracy. The assumption was that the more power a sensor consumes,
the more accurate it is. That's not necessarily always true so this
attribute is badly named (although the spec is pretty clear about its
real intent). Adding privacy semantics to this attribute is completely
misleading: its current semantics, controversial as they may be, have
absolutely nothing to do with privacy.

- we have an open issue to remove / rename this parameter in V2:


I therefore propose we leave the spec unchanged. In v2 we'll either
remove it or rename it to make it clear it's about power saving.
