What about having regulations updated instead of bending the industry backward to fit the outdated regulations?
It's similar to HMRC's "we can come after you for unpaid tax for 7 years", but you can only go after the HMRC for 5 years for overpaid tax.
The rules are ultimately for the benefit of long term investigations such as the LIBOR rigging, and Guinness trials.
