Setting getIDs permanently
<p>For business reasons, I have to capture the ID's of Views in my application.  Since I don't want the ids to change over multiple deployments, I have created ids.xml and public.xml as described here <a href="http://stackoverflow.com/questions/12334857/how-to-add-id-to-public-xml?lq=1">How to add id to public.xml?</a></p>

<p>I have about 200 ids on the app, and I need to capture only about 150 of those.  My question is, should I refer to all 200 ids in my ids.xml and public.xml OR just refer to the ones I need (the 150) would be good enough?
Thank you.</p>
