Bonsoir John,

One remaining question. If this extension is "only a helper and MUST NOT be
used to (in)validate a certificate chain" as you say or as the spec says
"non-critical", then why does 'openssl verify' reject this chain?

That’s an open question. This topic has been raised on IETF PKIX last april. The normative validation algorithm in section 6 of RFC5280 doesn’t use AKI/SKI. RFC4158 is about path construction and is also clear on not using AKI/SKI to eliminate a certificate chain.
