Is it even possible to distill V8 into a single Windows DLL anymore? The version I use was about 3.5 MB in 2013. I tried updating it a couple of years ago, but quickly gave up and backed away, groping for the doorknob.
It's possible though not straight-forward. React Native Windows seems to have a version of V8 wrapped with JSI (for use in React Native) though by the looks of the project, it appears to be only used internally and not really meant for stand-along consumption: https://github.com/microsoft/v8-jsi
