[Gluster-devel] GF_FOP_IPC changes

I've been looking at the recent patches to redirect GF_FOP_IPC to an active subvolume instead of always to the first. Specifically, these:
http://review.gluster.org/11346 for DHT
http://review.gluster.org/11347 for EC
http://review.gluster.org/11348 for AFR
I can't help but wonder if there's a simpler and more generic way to do this, instead of having to do this in a translator-specific way each time - then again for NSR, or for a separate tiering translator, and so on. For example what if each translator had a first_active_child callback?
xlator_t * (*first_active_child) (xlator_t *parent);
Then default_ipc could invoke this, if it exists, where it currently invokes FIRST_CHILD. Each translator could implement a bare minimum to select a child, then "step out of the way" for a fop it really wasn't all that interested in to begin with. Any thoughts?
