Thanks to shed some light on this!
The use case i had in mind was offloading of processing to another computer. A common complaint i see is that mix engineers/producers run out of cpu resources when they run plugin-heavy sessions. There are some options out there that let you run vst’s on different devices, but that is still an additional layer of software. So when i saw this flag i got curious whether this could be a solution.
Of course, if no hosts support this, then it won’t fly. A chicken/egg problem, i guess.
Keeping the general idea of separating UI and processing completely does seem right. For example, with the recent announcement of SOUL, it could become more common to run processing elsewhere. But there again the same goes: sufficient market adoption will be needed.
