@murks @unfa @unfa depends on what you mean by "chance".
I have many high-quality LV2 plugins installed on my system, all of them opensource. For Linux-audio, LV2 was/is the format to go for a long time. Other systems have other formats that are more popular.
Anyway my point is - depending on your usecase and point of view, LV2 can be considered a success already. People have been using and developing for LV2 already for many years.
Popularity contests are a bit meaningless in opensource.
