Source/WebCore:

The target-densitydpi parameter was originally implemented on Android,
but it does not appear to be widely used and introduces significant
implementation complexity because it forces us to track three scale
factors (defaultDeviceScaleFactor, deviceScaleFactor, and
pageScaleFactor) rather than just two (deviceScaleFactor and
pageScaleFactor).

There don't appear to be many web sites that use target-densitydpi
because it is not supported on iOS.  There are also concerns from the
standards community about the design of the feature.  It seems our best
course of action is to remove target-densitydpi and address these use
cases via other mechanisms, such as responsive images and device units
in CSS because those approaches are likely to be implemented broadly.
