We called this HeadersOnly for the consumers. That may not be the right answer here but this feels weird.
Maybe KeysOnly?

I wanted HeadersOnly, but that name already declared in the package. Although I originally though of this as a way to improve the Keys() method performance, I realized that it would not be unreasonable for someone to just watch the key and not care about the value change, just the state change, which comes in the headers. Maybe StateOnly? EntryStateOnly? MetaOnly, EntryMetaOnly?

I would be ok with any of the following. Will let you and @ripienaar decide ;)
KeysOnly
MetaOnly
OnlyKeys
OnlyMeta

My 1st choice is MetaOnly, 2nd is OnlyMeta. I think Keys isn't correct as we will end up returning an entry object with everything except the value, the "meta" part of the entry as described in the ADR.
