Virtually nothing? I can't think of anything you'd likely get out of destroying a 25+ year old will. There are time limits for most claims against the executors

Virtually nothing? I can't think of anything you'd likely get out of destroying a 25+ year old will. There are time limits for most claims against the executors. They are also planning to keep some number of wills, if you kept say everything over a certain value you'd probably cover the cases you're imagining.
