Does Dendrobium moniliforme need a dormancy to stay healthy?

I've heard that in Japan, because Dendrobium moniliforme is usually grown for its foliage, it's pretty common for growers to keep their orchids at constant temperatures throughout the year, so that even though they don't flower, they have continuous growth and keep their leaves.

Is this safe for the plant? I thought orchids that have a Winter dormancy end up exhausting themselves? At least that's what I've heard for Sedirea japonica, and some types of Dendrobiums like nobile.

How long can a Dendrobium moniliforme be kept in a 'seasonless' state, before it starts to develop problems? I like the leaves myself, but should I force a dormancy when Winter comes around by decreasing the temperature? Also, how cold does it need to be? Hopefully no colder than 10 C.

ADDENDUM: To be honest, now that I think about it, I don't know if Dendrobium moniliforme even has a dormancy or not? Like, I know it can handle really cold temperatures and it is deciduous, but now that I think about it, I remember seeing once in a video MOG was talking about her Dendrobiums and said that there are some that are deciduous but don't take a full Winter rest. Is Dendrobium moniliforme even one that takes a rest?
