axis.line.x and axis.line.y do not set the theme for the x axis line and y axis line as expected.
Minimal reproducible example:
p <- ggplot() + geom_blank(aes(x=1:10, y=1:10))
p + theme(panel.border=element_blank(), axis.line=element_line()) ## works
p + theme(panel.border=element_blank(), axis.line.x=element_line()) ## does not work
p + theme(panel.border=element_blank(), axis.line.y=element_line()) ## does not work
It is possible to set just one or the other by setting axis.line then turning one "off":
p + theme(panel.border=element_blank(), axis.line=element_line(), axis.line.y=element_blank()) ## works
But I don't think this is how it's supposed to work.

This sounds like a great feature, but unfortunately we don't currently have the development bandwidth to support it. If you'd like to submit a pull request that implements this feature, please follow the instructions in the development vignette.
Thanks for this post and work-around.
I just want to say that this issue does not exist for axis.ticks.x and axis.ticks.y
