> The real problem with all these sorts of things is network effects. People aren’t going to use the Rust port of postcss unless the plugin they want to use works in it, and it can be conveniently tied into their existing toolchain, and—— and—— I've never used postcss, but I don't think this is strictly for all js build tools. There's libsass, written in C++. I've mentioned flow. I'm sure there are others. I think you're right though that webassembly is going to be big for this kind of thing.
