Maybe open_file() should actually be called open_path_or_stream() as it's a wrapper around open_path and open_stream.

Do you also know why the test coverage went down so much?

I think the patch target checks coverage for changed lines, and for several adapters there are no tests yet. As I touched those lines they are taken into account when calculating the code coverage of the contribution.
