Perhaps it is the same as any other trait, you would need to select for genetics having a highly developed proventriculus to see if it would be an effective resistant mechanism before writing it off as ineffective.

According to our State Apiarist; and I will quote him as he told me this personally during a lengthy discussion.  'A highly developed proventriculus is the mechanistic for foulbrood resistance.'  'If a colony contracts foubrood, in any stage, it is NOT resistant to foulbrood, otherwise they would not have contracted the AFB.' 'Hygienic colonies that contract AFB, -even in the very early vegitive stage, are NOT resistant to AFB, or they would not have contracted it' 

The State Apiarist sent me a few manuscripts, but I did not save them.  I believe a google search " proventriculus - filtering - AFB " will bring them up, or other similar studies.

Best Wishes,
Joe
