I wouldn't say that it is, especially where it's grown in Costa Rica - which is similar to where the plant originated. Being that the climates are somewhat related, it wouldn't require too much more to make up for any stresses put on it.

However, there are areas that had been affected by some depletion due to simply not understanding proper farming practices. I don't think it's too serious today, since they've been really staying on top of things with NPK fertilizers and foliage treatments when needed. If they had not started doing that, they'd be in a lot worse shape. Now they're all moving toward better sustainability practices, which includes the companion growing and natural fertilization from that, plus the NPK as needed. Things are definitely improving overall.

They just have to keep an eye on temperatures now. They've had a little warming over the past several years.
