In a slight research detour I came across an item of possible interest to those who aren't familiar with it (as I wasn't until today). It's the publication of articles from a conference on small millets 36 years ago

Seetharam, A., K.W. Riley, and G. Harinarayana, eds., 1989, Small Millets in Global Agriculture: Proceedings of the First International Small Millets Workshop, Bangalore, India, October 29 - November 2, 1986. Oxford & IBH Publishing Co. Pvt. Ltd., New Delhi.

A summary of recommendations from this conference is presented at http://www.milletimplic.net/englishinfo/1stintsym.htm

One of the editors of that volume, Kenneth W. Riley, gave a summary of some of the ideas and hopes of that time, in "Small millets with big potential : introductory remarks" (1987):

Personally I find it of interest to see where the thinking was at that time. Some of the articles give the state of use of and research on specific millets. Keep in mind that this event was held in a period when in much of the world, millets were already losing ground (literally, in terms of area cultivated, and figuratively in terms of dietary habits) to the major cereal grains most of the world depends on. So this compilation may be useful for historic perspective.

While on the topic, there was a follow-up event five years later in Bulawayo, Zimbabwe. That Second International Small Millets Workshop also had recommendations: http://www.milletimplic.net/englishinfo/2ndintsymp.htm

The proceedings of that second conference do not appear to be available in full online, but were published as: Riley, K.W., S.C. Gupta, A. Seetharam, and J.M. Mushonga, eds. Advances in Small Millets, 1993, Oxford & IBH Publishing Co. Pvt. Ltd., New Delhi.

Note that "small millets" explicitly excluded the "large millet(s)," pearl millet (and sorghum).
