This decisions looks well-reasoned. It acknowledges the strengths of their current implementation, and explains why another language may serve their goals even better. I can follow along as someone interested in general software decision-making, even though I'm not particularly invested in either language. One specific thing I like is that the motivation for this rewrite is organic, i.e., not driven by an external pressure campaign. It's refreshing to see a drama-free rewrite.
