I’ve heard this before but I’m skeptical about this approach. It’s got to cost close to 2x to develop and maintain two stacks — if they’re sharing a lot, that would defeat the point. Then you’d have two stacks tested about as well as the one today. Instead, you could put that investment towards testing and improving quality on the one stack.
I know a second stack hopefully has different bugs. But is that likely (to a meaningful extent)? Reimplementations often reintroduce old issues (which suggests many people make similar mistakes), plus it’s hard to imagine the first stack not influencing the second in various ways.
