functionality missing from ggplot2?

[bbolker]

as discussed here, there still seem to be a few pieces of ggstance functionality that don't exist (yet?) in ggplot2

• vertical dodging (position_dodgev)
• horizontal orientation of line segments in legends (geom_pointrangeh vs. geom_pointrange(xmin=..., xmax= ...)

Perhaps this is better for the ggplot2 issues list, but can you shed any light on whether (1) these are already implemented in some way in ggplot2 but I'm missing them or (2) there are plans to migrate this functionality to ggplot2 ?
