Why is the position being removed from remark output

src/remark-remove-position.js

Forgive me for putting this so bluntly, but…WHY? I was using documentation.js to parse documentation and extract code blocks for [ferrum.doctest](https://github.com/adobe/ferrum.doctest) and my build is failing because of the removal of the position?

I am perfectly happy with the upgrade, but removing the position might better have been a breaking change oO
