Looking for a way to change the Modifiable visibility

[ChrisTrenkamp]

I'm using a custom Immutable style:

@Value.Style(
    typeImmutable = "*Impl",
    typeModifiable = "*Modifiable",
    visibility = Value.Style.ImplementationVisibility.PACKAGE,
    overshadowImplementation = true,
    implementationNestedInBuilder = true)
@Target(value = {ElementType.TYPE})
public @interface CustomImmutableStyle {}

I prefer this style because it keeps the builder public, while hiding the *Impl class from the API. This keeps things clean and simple.

However, I'm in a situation where using a *Modifiable makes things easier (I need to access some fields before it's done building). The visibility style is putting the *Modifiable class at the package level, so consumers of the API don't have access to it. My only choice is to make the visibility public.

Is there a way to make the *Modifiable class public, while keeping the *Impl class at the package level?
