Why do that?

Have you tried overriding the PropertyPersistenceStrategySource implementation:
<implementation
service-point="tapestry.persist.PropertyPersistenceStrategySource">
<invoke-factory service-id="hivemind.BuilderFactory" model="singleton" >
<construct class="MyPropertyPersistenceStrategySource" >
<set-configuration configuration-id="PersistenceStrategy"
property="contributions" />
</construct>
</invoke-factory>
</implementation>
class MyPropertyPersistenceStrategySource
extends PropertyPersistenceStrategySourceImpl {
public void setContributions(List contributions)
{
List adjustedContributions = new ArrayList(contributions);
//remove the PropertyPersistenceStrategyContribution whose
//getName() returns a string starting with "client".
super.setContributions(adjustedContributions);
}
}
