I've heard mention that delegated datasets and "reprovisioning" (by this I mean 
re-creating the zone with a new template, but the same delegated dataset) are 
the "way of the future" -- or at least a good way to handle upgrades in the 
long term. It makes good sense to me, and I've already been taking steps to use 
it, developing internal templates that keep all their individualised data on 
the delegated zfs, and when a new zone starts up, checking for its presence and 
using it if already available.

However, there's no way to use delegated datasets from the SDC CloudAPI at the 
moment, and when I asked on IRC, the only answer I got was that there are no 
plans to change this. If I want to use delegated datasets and SDC in the near 
future then, it seems my only option is to write services that talk directly to 
VMAPI, which as I understand it is considered unstable.

So I have two questions: how unstable is "unstable" with regards to VMAPI in 
SDC7? I note the ops portal seems to have support for it already.. does that 
mean it's less likely to change? And secondly, are there any dissenting 
opinions about the utility of delegated datasets that might be interesting to 
hear? Are there concerns / problems with it that are the reason why this 
feature has not progressed, or is it just a case of manpower being directed 
elsewhere?
