It's an introduction to a Go change proposal, stating a premise that the Go devs share even if you don't; it's like the intro to a C++ change proposal referring to C++ as a good embedded-systems language and the STL as a versatile, easy-to-use data structures library. You can argue, but that's not really part of the conversation about the change any more; you're going off and starting your own conversation about what languages people like. (The plan to transition over by automatic translation, not the bullet points up top, is the interesting part of the document to me. I hope they're able to achieve it without too-serious compiler-performance regressions, since I really like the zippy compilation I get now.)
