In SegmentFetcher, if data without finalBlockId, it will emit next Interest. In NfdStatus::fetchVersionInformation(), NfdStatus emit "/localhost/nfd/status", but statusServer doesn't have publisher, which means it can't set finalBlockId in Data, and it doesn't have second data. So it will fail to fetch "/localhost/nfd/status". Add setFinalBlockId in statusServer can solve the problem. Other fetch can be rewrited using SegmentFetcher successfully.

ForwarderStatus is not StatusDataset, so fetching it is a simple Interest, not SegmentFetcher.

So we don't rewrite NfdStatus::fetchVersionInformation() using SegmentFetcher, just express one Interest?

note-5 is correct. SegmentFetcher is only applicable to StatusDataset.

Why isn't validation done in the code?
SegmentFetcher validation API is incomplete, see #2734.
There isn't a solution for how to obtain NFD's public key.
It should be an out-of-band method, such as reading from a file (owned by root, 0644 permission).
