The following references would seem relevant for what a "typical" mathematician might think coming to Sage who isn't directly involved in either kind of lattice on a daily basis, though it's not clear that it resolves this discussion, since the authors below are self- selecting. The idea that a "point" lattice (and hence Euclidean lattice) is a special case of a "poset" lattice is interesting, though I don't see how would that work for the cocompact definition or for unordered fields...
