I figured that most types that represent some kind of textual output would have a Show instance. Is there a good reason why your type doesn't?

Would it be hard to wrap it in a newtype and define a dummy Show instance for that?

Oh yes, that's true. There are certain places where we need to downshift some inline content to plain text (e.g. in generating alt tags for images).

Looking more closely: in core commonmark, `toPlainText` is only used in SourceMap and in Html. So you shouldn't have a problem there. In commonmark-extensions, as you note, it's used for...

Anything that involves a change to the pandoc AST is very involved. Changes would be required not just to pandoc-types, but to the majority of modules in pandoc. We are...

I'd consider a syntax extension for `==` in commonmark-extensions -- since this is started to get wider support -- but the pandoc change would be more controversial.

There is no commonmark renderer in this library. The library does, however, track source positions of everything. You could use that to delete sections from the original file if you...
