Well that's not quite true. Unless you discount Tar as a seldom used, almost unknown obscure application.
The fact is that, generally, a program that relies on tar (for example, Amanda) to create incremental dumps should be able to get a proper ctime for each file. See the "-g" option on the GNU Tar manpage.
There might be other tools that depend on current ctime behaviour. Somehow I don't think that breaking people's backups is the way to go, so a separate field seems rather wiser.
