I went back and reread this. The text:
2.2.2. Hop-by-Hop Options Header
The hop-by-hop options header, when present in an IPv6 packet, forces
all nodes in the path to inspect this header in the original IPv6
specification [RFC2460]. This enables denial of service attacks as
most, if not all, routers cannot process this kind of packets in
hardware but have to 'punt' this packet for software processing.
Section 4.3 of the current Internet Standard for IPv6, [RFC8200], has
taken this attack vector into account and made the processing of hop-
by-hop options header by intermediate routers optional.
I don’t understand why this is talking about RFC2460 at all. Seems like it
would less confusing to only describe what is in RFC8200. Nor is “punt”
correct way to describe this. Way too colloquial.
Describing RFC8200 behavior as “optional" is quite right, RFC8200 says:
...now expected that nodes along a packet's delivery path only examine and
process the
Hop-by-Hop Options header if explicitly configured to do so
It’s not optional if configured to do so. It would be better to use the
RFC8200 words.
Lastly the “Original" IPv6 Specification was RFC1883.
Bob
p.s. I agree about the references to RFC 3068 and RFC 3627.
