I'm not claiming you claimed it was a simple specification :-)

I just find it interesting. This would indicate to me that there are 500 "features" in the language. I thought mark-down languages just provided a few shortcuts for producing the most commonly needed HTML features and then provide a fallback to HTML. So if you cannot do it in the markdown language, use HTML instead.

I can't really be bothered to take a look at the tests, but I strongly doubt there are actually 500 features. A large part of those tests are probably trying combinations of features. E.g. suppose markdown only had tables as a feature, and nothing else. That feature alone deserves several several tests (for tables of various sizes, edge cases such as having only the header, having rows with an incorrect number of columns, etc.).

But let's assume we can get away with just a single test for tables. And then we introduce the features "section headers" and "bold" and "underline". All these features can interact (e.g. underlined bold section headers), so we want to test combinations of all those features, and have a nice combinatorial explosion.

I see, combinations. But also the ability to use different combinations of "basic" features in a sense are a specific feature too. Like you can mark text bold and you can mark text as representing a table. But can you mark text within tables bold? If you can that would to me be a "feature" too. If you can not, then that "feature" is missing.
