I tried that and it doesn't work very well.  The service jar will need 
to depend on classes in WEB-INF/lib.  So the dependencies get hard to 
declare in module.xml.  A user might not even know how to do it.

So it really needs to "look" like it's sitting in WEB-INF/lib.  I see 
the code in WebStructureDeploymentProcessor that adds ResourceRoots to 
Attachments.RESOURCE_ROOTS.  I'm wondering if that is the way to 
accomplish this.

Yea, I don't want to do that.

I don't understand what you mean by "exactly deployments".
