how would it manifest to a user?
A normal user won’t notice the difference.
By the way:
Support for a true debug build. Developers no longer need to add the android:debuggable attribute to the tag in the manifest — the build tools add the attribute automatically. In Eclipse/ADT, all incremental builds are assumed to be debug builds, so the tools insert android:debuggable=”true”. When exporting a signed release build, the tools do not add the attribute. In Ant, a ant debug command automatically inserts the android:debuggable=”true” attribute, while ant release does not. If android:debuggable=”true” is manually set, then ant release will actually do a debug build, rather than a release build.
