Ah, that's a very good point.  I didn't consider the significant range
differences between a double and the required minimums (and the actual
maximums that browsers use).

We've made it a SHOULD now, so that it's legitimate to have things
work correctly if it's parseable into a double, but violate if it
would require custom parsing to capture the difference.  Is that
