Hmm. If we go down this road I would make the choice of simplicity
and remove entirely a column, then, generating the snakecase from the
camelcase or vice-versa (say like a $string =~ s/([a-z]+)/$1_/g;),
even if it means having slightly incompatible strings showing to the
users. And I'd rather minimize the number of exceptions we need to
handle in this automation (aka no exception rules for some keywords
like "SSL" or "WAL", etc.).
