META-INF/services no longer accessible by default from dependencies

With WFLY-9375, META-INF/services are no longer accessible by default from dependencies as would be expected. This could still surprise some users who were dependent on the old, technically broken behavior (services accessible by default). So for instance, if they had a SCI in a global module, this will no longer be invoked on 7.2 unless they add services="true" (https://access.redhat.com/solutions/3901591).

Documenting this change of behavior could be helpful.
