I think there's a lot less (or maybe more, depending on how you look at it) to this topic than the article suggests.

I think the significance of it depends on how accurate the article is.

"the botanists voted on a measure to leave the lengthy and time-consuming descriptions behind."

Something got lost in translation between the original article in PhytoKeys and that person's blog entry. All the new rule does is allow English to be used in place of Latin.
