I state it more or less explicitly in my first email (the one I accidentally
sent just to fantasai first), but it's clearly implicit in many of the
emails.

Boris argues a subtle line, where he advocates clamping the computed value
only.  The actual value of font-weight can vary upwards and downwards
indefinitely (or rather, until it overflows whatever the browser is using to
store it).  This would be completely acceptable, as it would still achieve a
symmetrical effect.
