Both of the following example actually only tells you how to set them, not how to use them and both are optional.
Given the fact that there are only 20 bits in the flow label, then globally only 4K flows can be defined - is that enough ?

Nobody is going to publish that sort of competitive data. As noted earlier, this is quite likely to be either qualitative (ability to classify ESP traffic) or simply a matter of heat dissipation and the marginal cost of a chip set.
