@cstross Not just crimes, but also SIGINT. Worked example: in 2015, the NSA released William Friedman's papers. He retired in 1955 and died in 1969—but some of his papers were still withheld and others were redacted. And he filed a patent application in 1933 that for security reasons wasn't issued until 2003 (https://patents.google.com/patent/US6097812).

  Cryptographic system
  
  The crytographic system automatically and continuously changes the cipher equivalents representing plaintext characters so as to prevent any periodicity in the relationship. The system has a series of juxtaposed, rotatable, connection changing mechanisms to provide a large number of alternative paths for the passage of an electric current corresponding to a message character. Further, the system has parts for the irregular and permutative displacements of the members of a set of circuit changing mechanisms to thwart cryptanalysis.

  Apple wouldn't be doing this—at considerable expense—if they didn't consider such attacks to be plausible within the relevant lifetime of currently intercepted and retained messages (ie. not necessarily today, but within the statute of limitations of any crime you might be confessing to in an iMessage).
