Sure. dvh was commenting the variety of ways the f phoneme can be written down in different english words, and for the purposes of the discussion, elthran's conservative line on where does the english language end is not really super useful. Having 5 or 6 different symbols for a single sound is irrelevant; the point is that the article is considering letters as whole symbols for a sound, when they might be part of a symbol, not the whole symbol, for a sound. If gh is /f/ in a particular word, then using that word as part of the g cancellation is wrong.
