Yes, we need to consider that.
I rather hoped I was being agile by ignoring it until (if) it ever became a problem,
as the overwhelming majority of wild gribs use 'i scans fastest'.

I'm still adjusting to the agile way. It does seem wishy-washy as to what's "being agile" versus what's "leaving a gaping hole" but I think this is the right way to go, otherwise we'd have to cover everything, writing lots of code that nobody needs...? What are your thoughts?
