Peter:
The addition of SubjectKeyIdentifier to SignerInfo was considered. Many
developers felt that backward compatibility with PKCS#7 v1.5 and S/MIME v2
was more important that the shorter certificate reference.
It woulf be very easy to add SubjectKeyIdentifier to SignerInfo if the
group concensus has changed.

I've noticed that RecipientInfo identifies a key with a CHOICE between
IssuerAndSerialNumber and SubjectKeyIdentifier, but SignerInfo only allows
IssuerAndSerialNumber. Presumably whatever reason requires the SKI in the
RecipientInfo should also require it in the SignerInfo, could these be merged
to create a unified identifier type (ie they both use a RecipientInfo-style
CHOICE)?
