Is there a special reason not to repeat the domain (apart from avoiding
redundancy) ? 
When I edit services using Protege (and OWL plugin), it seems that I
must add the domain for hasInput and hasOutput properties. If not,
Protege only allows me to use the hasParameter property (it does not
include reasoning to deduce this kind of domain inheritance). 
However, this kind of troubles may be solved by the (future) OWL-S
editor :-)
