We could ask the proponents of new algorithms for information on current or expected usage. However, if adoption is relevant to any kind of decision on what to do with an algorithm proposal, this should better be formalized somewhere and applied evenly to all algorithms that may appear in the future. Personally, I think that some expectation of adoption would be useful not to clutter the list of algorithms, but the threshold should be quite low.

Also, as the IETF is the global SDO for DNS, it should make sure to encompass the needs of all Internet communities around the world. If a local community wants or needs for any reason to use a "globally non-standard" algorithm, there should be ways for this to happen without asking them to prove adoption of that algorithm on a global scale. Eric's points on fragmentation, implementation burden, potential incompatibilities are valid, but they should play out at usage level, not at the standardization one. We should just make it clear to proponents that adopting a rare algorithm may make them incompatible with the rest of the planet, but whether this is acceptable or not is up to them - and they may even not have a choice, due to non-technical factors which won't be affected by whether we recognize the algorithm or not. In this regard, having an intermediate "supported but not globally recommended" classification level, with lower procedural barriers, seems like a useful thing to me.
