This is way too early to remove support for something that has been
in place since 2012. As you've just shown, people are using it with
DT files today. We don't know how long people will persist using
older files, and we don't know whether there are DT files out in the
wild that we don't know about.
Our general rule is that we maintain compatibility for older DT.
NAK.
