This is a good first issue because there is no API design and does not require any understanding of Matplotlib internals.
Labeling this as medium difficulty because the implementation is likely to touch the objective C code and may require familiarity with both Python and objective C. This may require research into the underlying toolkit's API.
Just to clarify, that offset is in the "dash-space"? (I first read it as x and y offset.) I guess one can possibly even use the new striped line functionality for this?

In the Qt backend, we draw the rectangle twice, once in black, once in white with an offset. The same can be done in the macos backend.

In all likelihood it will be much faster to do this with calls to native (dashed) path-drawing functions.

Yes, in dash space. Both Qt and GTK draw them with native calls.
