Actually it depends on commonmark spec and recommonmark implementation.
If any commonmark notation are not supported by recommonmark, please report it to https://github.com/rtfd/recommonmark/

Can we add this info to the docs somewhere?

Documented at #3373.

what about the support of GitHub Flavored Markdown (GFM) ?
it is certainly one of the best flavor (until included in CommonMark ?) and could be the missing build chain item for serious integration !

AFAIK, there are no way to handle gfm files.
Your contribution is always welcome!
