Sean,
1. Implenations MUST have absent parameters for SHA-2 -- there is no reason
to allow anything else to run. I won't dispute the MUST read with NULL
parameters however much I would like to. The defect does not really apply
as plenty of time has passed and this is a new algorithm. The only
exception to this appears to be in OAEP and PSS where the parameters are
explicitly defined as being required.
2. Why allow for optional parameters on the signature algorithms for rsa -
not permitted for sha-1WithRSAEncryption.

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the S/MIME Mail Security Working Group of
the IETF.
Title : Using SHA2 Algorithms with Cryptographic Message
Syntax
Author(s) : S. Turner
Filename : draft-ietf-smime-sha2-08.txt
Pages : 10
Date : 2008-9-26
This document describes the conventions for using the Secure Hash
Algorithm (SHA) message digest algorithms (SHA-224, SHA-256, SHA-
384,
SHA-512) with the Cryptographic Message Syntax (CMS). It also
describes the conventions for using these algorithms with CMS and
the
Digital Signature Algorithm (DSA), Rivest Shamir Adleman (RSA), and
Elliptic Curve DSA (ECDSA) signature algorithms.
