You do not normally need to check whether tactile feedback is supported or not, as it is safe to call the API functions even if feedback is not supported.
However, in some cases using the area registry can require complex calculations for e.g. at portrait/landscape mode changes. In case these calculations cause too much overhead, you can use the TouchFeedbackSupported function to check whether feedback is supported or not, and skip the calculations in case there is no feedback at all.
