If you define an update chain as default, then it will be used for all 
updates made where a different chain is not specifically requested.

I have used this personally to have my custom update chain apply even 
when the indexing comes from DIH.  I know for sure that this works on 
4.x and 5.x versions; it should work on newer versions as well.
