if `name` was used by any consumers you could use

```{
"name": Object1,
"new_name": Object1,
"name2": Object2
}```
until they move over to update to use `new_name` and then you could retire `name` field

The expand and contract pattern

thing is
• whole js is verified ( could be solved , theoretically )
• 2 objects ( `"name"`  and `"new_name"`) will not be send :disappointed:

&gt; The expand and contract pattern
this is known thing, but not applicable now :disappointed:

Ie the provider won't update their schema to support the old and new format? and will just do it in a big bang?

if so your consumer code will have to be tolerant to the fact that the property can either come from `name` or `new_name` (but would have to make the decision as to what it does if both are present, which takes precedence, especially fi they were different)

Yeah that sucks, this is where showing them how difficult it is to support at your side as a consumer, helps in discussing the impact of a change. If you have more consumers that will be affected, that can help your argument

this is just a string in general, just a name of the same object has been changed to more descriptive now
