I did something like this for the Sage project, but I did it on the tick 
formatter level. I just made a tick formatter that omitted specified 
positions. I've attached the "Selective Formatter" class. If anyone 
has comments, I'd appreciate them! Basically, I just replaced the 
formatter with the selective formatter, which passed things on to the 
previous formatter if the tick label was allowed.
It would be great if spines supported this sort of thing natively, but 
the flexibility of tick formatters seems like a nice place to handle it 
as well.
Thanks,
