Maybe they can call it "Standardized Markdown" which would be both more descriptive and accurate.
It would be best if the team would just go another route entirely.
To be honest, I think this industry wide devotion to Markdown is hilarious, since to me it's a pretty garbage way of solving an easily solved problem. The main/only thing in its favor is its ubiquity.
Whatever you may think of Markdown (that is markdown as created by Gruber), it surely isn't unreasonable to suggest that if any version can make that sort of claim, it should be the original.
Out of curiosity, what do you think is the better "easy" solution to the problem Markdown is trying to solve?
