Hey Parnassus,
I don't see it either, if you type "list" you'll see a list of all available commands on the level you are currently on. If you do that on the base level, there is no "show xxx split-recovery" command, so I do believe it's not available just yet.
Something that I'm missing as well is a "show active-gateway" of any sort, per interface or in general, there is not such command either.
Cheers!
Aarón
