Probably? It's public API, downstream projects and users decide what
they want to use based on their needs.

And in our tree it can for example be used to simplify the change i made
in a22c6a4796 and e91f0c4f8b, or in bitstream filters to allow changes
to be made directly to the input packet's data.
