[sutaakar]

Issue link

Intention is to align AppWrappers function with AppWrapper, so result of both functions can be used in transforming functions.

This should be:

for i, v := range aws.Items {
	v := v
	awsp = append(awsp, &v)

See golang/go#56010

Right, thanks for pointing it out.
I completely forgot on this "feature".
