Comment (by elenril):

 The reasons were already stated by people above:
 * `ffmpeg` CLI is an M-to-N transcoder, there is in general no canonical
 way to tell which is THE input file for a given output file;
 * Which timestamp of the three standard ones is to be preserved? Do we add
 a new option for each one? What about permissions, ACLs, xattrs, etc.?
 This is a giant can of worms.
 * The same functionality can be easily implemented with standard unix
 commandline tools.
 >͏    If the proposer would like to implement it: why not?
 Because `ffmpeg` CLI already has way too many options, which makes it
 extremely hard to understand both for users and developers. Each new
 option has to be maintained for a very long time, and its interactions
 with other options have to be considered, making future development
 harder. New options should only be added if there is a strong reason for
 them to exist and I see no such reason here.
