Wait, do grobs have a reference to the context?

I know you can use \applyOutput to process grobs at a given moment in 
time, and that provides you access to both the grobs and the context.  
And my snippet showed using an engraver to achieve something similar.  
But within, say, a stencil procedure, it seems like you only have the 
grob to work with.  Is there some ly:grob-context method that I have 
been overlooking?
