This is a good question, and I think this is similar to the the current and 
existing ugliness we have around marking parents down as well (which uses 
librecords and persistent metrics to store string values). That’s not great 
either, so a general concept of a persistent key-value store is needed already! 
I think your use case falls inline with what we need to do for the parent host 
up/down state as well, so even more reasons why we need that :).
