Usually, with a lot of products, the expiry date is just an indicator. I ate 12+ year old pastas, 2+ year old sauces I found in our pantry and they were indistinguishable from half year old items. Well, the sauces actually had a much better taste than the ones used before expiry.

I'd rather see an expiry date plus some indicator that after the expiry date how fast would it spoil, or what changes it will go through, if ever.
