Versioning the type/format of a property

[fzkhan]

Looking for a way to version the type/format of a property.
As an example, v1 will be:

model Product{
  id: int32;
  link: url;
}

and v2 will be:

model Product{
  id: int64;
  link: string; // This will remove the `format: uri` from the Open API spec v2
}

P.S. I am just 1 day into TypeSpec, but searching online I couldn't really find a solution for this. I saw in another thread that versioning model descriptors was not supported, is it the same for changing types? #6020

You can use @typeChangedFrom decorator from the versioning library https://typespec.io/docs/libraries/versioning/guide/.

Note however that using this will increase the complexity of your spec significantly specially if you start making non additive changes.
