This is an incubating project, so there are no api stability promises.  
If a patch breaks some functionality that we've decided to not support 
going forward I don't see a problem with it.  That said, if a patch 
breaks some functionality that we _do_ plan to keep, I'd prefer to see 
it done as a series of dependent commits that end with the feature in a 
working state again, even if some of the intermediate commits are not 
fully functional.  Hopefully that will both keep the commit sizes down 
and provide a definite path back to functionality.

This sounds reasonable to me.
