Is there a way to set different default values across versions?

[Chinonso Chukwuogor (nonsocode)]

Say I have a model defined with a default for one of its properties.

model Foo {
  bar: int32 = 1
}

In a future api, if I want to update the default value for Foo.bar while preserving it's previous value for the older API, is there a way to do this?
