So far a coordinate system always refers to the species or strain identified by its taxonomy ID. As you say, strains DO have their own NCBI taxonomy ID. It may be that this is not the case for a strain that someone wants to annotate, but I have yet to see an actual example. There is the wider question of how to handle individuals though. I can't comment on how 1000 genomes do this as I've only seen these data expressed as variations annotated upon the reference assembly, but my feeling is that if annotations of an individual were needed then it could/would be done using the assembly paradigm as a surrogate.
