Review Comment:
   Can you elaborate a bit more on your claim? Is it because you have to modify 
the interface for that change? 
   
   If you're concerned about chaning the interface: `JobGraphWriter` is an 
internally used interface (i.e. not marked in any way as `@Public` or 
`@PublicEvolving`). Additionally, it's not really exposed to users in any way I 
could think. In this sense, modifying the interface in order to improve the 
overall code base (rather than introducing some workarounds) seems like a 
reasonable approach. WDYT?
