I'm sticking my oar in here, and probably this is obvious, but anyway...

Surely it has to be "one taxid == one strain == multiple assemblies"? And this
isn't just for Bacteria, but all organisms. After all, "the" human sequence
has already gone through several revisions (hg18 and hg19 being the latest).
Even things like the E coli K12 sequence have gone through multiple revisions
after publication.

What about multiple individual genomes from the same taxid? What I am
thinking of here is different human genomes - do we call Craig Ventor a
strain of human with his own taxid? That doesn't seem like it will scale well ;)
Would we have an extra level here,
i.e. one taxid == one strain == multiple individuals,
one individual == multiple assemblies
