What isn't noted there is that we're still parsing the old format in some cases, see f9dbb64fad (config: parse more robust format in GIT_CONFIG_PARAMETERS, 2021-01-12). But I suspect you mean that you have your own parser that expects the old format only, I didn't find which way it was by grepping git-cinnabar's sources.
