Not enough of an advantage for me personally to have gone
and written it myself ;)
I can see some benefits in extracting information from the
NCBI identifier and storing them in the SeqRecord's dbxref
list and annotation dictionary (as consistently with our other
parsers as possible) if you are going to want to use those
Perhaps Keith can explain his interest with some examples?
