As long as you stick to the APIs, you can do anything you want. The API
contains mostly interfaces, but if there are any concrete classes in
there, you're free to use them.

Yep, but that's because the implementation of those objects is hidden.

The VariantKey is as simple value object (like a string), so can be
instantiated as is.

Might make sense indeed, though I'd rather add it as a static method on
the VariantKey object. Or we could at least define the -1 as a constant
somewhere.
