That would be one way. However, since it actually is a majority of the instance types[1] that support this feature, I'd vote to make it the default. That's unless it prevents using/booting the "small" instances of course, what AFAIK isn't the case --- I was able to create a snapshot ami from an F21 instance, register it with the sriov flag and boot both a t2 and an r3 instances without any issue and confirmed the sriov flag was in effect on the r3 instance. The only limit I know of is the ami has to be HVM[2]. Moreover, the feature is for free, no extra charges apply so why not to take advantage of lower latencies on the instances.
