Dear Mette,
We tend to consider bugs high priority, but sometimes, as in this case, the issues are just for us to not forget ideas and so they can stay open for a longer time.
Frankly, this is not a hard thing to implement, just that there was never any high priority case as one could "hack around it", but if you need it, I don't mind just writing the little bits of code to get it done fast. In the issue discussion there was a concern about getting the best API, which we might eschew in favor of just getting it doe.
Best
Luis
