Possibly it is worth adding new compiler features to address your 
concern, but the approaches I've used are:
1) Open all of the "extra" handlers in your project's main module, or
2) Add an extra page in your main module that contains links to the 
handlers that you want to ensure are kept.  Presumably you don't ever 
give out the URL of the dummy page.
