True. But we don't care nearly as much about homophony as about synonymy.

Homophony is a heightened concern for things primarily intended to be
conveyed over the phone (eg PGP fingerprints). Our primary concern is
rather that the things can be memorized — and memory, at least for
phrases rather than isolated words, is semantic.

E.g. we would not drop 'goat' just because we have 'coat', even though
the two are very similar phonetically (just one voicing difference).

While we're at it, homography is also a lesser concern — it'll mainly
come up when ensuring that parsing is unambiguous. (Granted, that's a
significant caveat. :-P)
