Sure, there will be deformations due to sagging and stress, not to mention shifting on the seabed. However, the hole was first spotted Dec 1994, if you believe the Swedish guy who claims he was called as a diver within days of the acccident, or if you don't find him credible, then at least since 1999, when the Swedish papers reported his claims. That type of wear and tear - an impact hole in the starboard and a petalled small hole in the hull port bulkhead - does not happen within two months or even 26 years if it was there all along and not due to wear and tear. Wear and tear stress do not cancel out the damage to the hull before it sank.
