My big question whether use of Key Wrap (RFC 3394) is recommended or not.

My intuition is is that the integrity check (see section 2.2.3 of http://www.ietf.org/rfc/rfc3394.txt )
does more harm then good in providing necessary integrity checks.

I assume that this has been discussed somewhere, but my Google-fu is failing me today.
Pointers to the literature would be welcome.
