I would expect the file datetime to be always preserved as it is
information about the file at the time of checkin.

That is the current behavior of subversion. What is being proposed here
is to extend the functionality to
allow for the saving of the modification time when a file is commited to
then give the user three
options of what to set the file datetime to:
1) The current time
2) The time of the repository checkin
3) The original File datetime.
