   It's more than that. You also need to update APIs for example to retrieve it 
and define what kind of relation it will have in the future when we have dag 
versioning and ID will (likely) change it's meaning of being name. And you need 
to define how it behaves when  you have duplicate names (can you?) and define 
what to do if some of your dags have name and some of them not, and probably a  
number of changes it causes. Should you be able to query tasks by name? Should 
you be able to search by it? What should it look like in the UI when different 
name was used in the past and changed? Should we keep the history of those 
names? 
   
   Those are just first few questions that pop in my head when you say "this is 
a cosmetic change".  
   
   IMHO - It is not. And we need to introduce such changes only when we know 
how it fits in the bigger vision of dag versioning. But that's my opinion only 
so I wonder what others think abou it too.
