It is if you want to preserve the date to indicate something, like
recording date or order. Metadata is probably better for that, but
there may be programs which can't access or present that. Think file
system listings.

To come to a solution for this: Any other program "suffers" the same
issue as ffmpeg, it has to do tricks to preserve the date. Better you
do it from an OS perspective. Under Unix, it's easy:

$ ffmpeg -i original_file.mov [...] new_file.mov
$ touch -r original_file.mov new_file.mov
(Using "-r", this tells touch to modify the date of "new_file.mov"
using "original_file.mov" as a timestamp reference.)
