Detailed docs were omitted before (and QTextMarkdownImporter::Feature is not public) because - "GitHub dialect" is a moving target (although we may have supported all known features when it was introduced). We should reserve the right to add to the feature set accordingly: so the numeric flags can be expected to change. - the writer mostly ignores the feature flags and writes back to GitHub dialect; only the front matter can be omitted that way - recognizing non-URL links seems fuzzy; md4c does it, so we allow that feature, but if it goes wrong it would be an md4c bug - hex flags look strange: in fact they come from https://github.com/mity/md4c/blob/master/src/md4c.h#L306 If we assume that they might change, it would be better not to document the numeric values in detail. But so far, md4c has never removed any, only added a few (and we don't yet support all the new ones).
