Sensible change. But I wonder if it will encourage retailers to treat the secondary now more food safety related "use by" date as the real "best if used by" date.
If you're like me and slightly paranoid about food expiration dates and sometimes checks things in corner stores, you might notice they like to sell items that can be razor thin on the "sell by" date.
That's exactly the problem attempting to be solved. There should be no problem with a retailer selling a product up to the sell by date, but you are still not keen to buy it because we don't know how much longer after that we have.
Instead you will be able to decide how close you want to cut it to either date.
