Until TeX Live 2018, MetaFun worked in plain (at least the subset I'm using). It would be a shame if the support would end. I also think that there are quite a number of users. The number of posts on TeX Stack Exchange mentioning luamplib with metafun is not negligible. https://tex.stackexchange.com/search?q=mplibsetformat I (and probably a lot of other people) would really appreciate if you could apply Luigi's fix, so we can continue do enjoy MetaFun, even outside ConTeXt.
