I notice that you did not include 32.5, which argues for what constitutes an incorrect original spelling:
But, wait, there's MORE!
"29.5. Maintenance of current spellings. If a spelling of a family-group name was not formed in accordance with [Article 29.3] but is in prevailing usage, that spelling is to be maintained, whether or not it is the original spelling and whether or not its derivation from the name of the type genus is in accordance with the grammatical procedures in [Articles 29.3.1] and [29.3.2]."
OK, this fixes Ceratopsidae.
I think I'll end this here.
