According to the patch notes:

New gathering points requiring a high Gathering rating will be introduced in patch 2.2. In preparation for this change, actions can no longer be used to improve the gathering rate of items at 0%.
* Gathering rate will only reach 0% when accessing certain high-level gathering points with an extremely low Gathering rating.
Will you gather up excess and cheap Gather's Guerdon materia to try and turn a profit with 2.2?

I picked up a few to see if I can cash in later as people scramble to meld their gear with + to gathering.

Edit: I assume most level 50 miners/botanist will be able to gather from the new nodes; however, I think the new nodes will have low success rates unless you use abilities or meld more +gather into your gear.
