It is perfectly valid to originate packets with Hop Count set to zero. Such packets, if received, must not be forwarded. However they should be accepted by a receiving node to which these packets are sent to.
Is this a feature or a bug?

Don't know about the sending host, but perhaps the next forwarding hop should send an ICMPv6 parameter problem message (RFC 2463, section 3.4) if it gets a packet with Hop Count = 0?
Trouble is, the original source of the IPv6 packet might be different than the previous hop which made the mistake forwarding the packet with Hop Count = 0. So, the ICMPv6 parameter problem message might be of little value to the original source.
