If I'm writing a code base that will likely have a >5 year life

... then don't write it in a language with negligible documentation, negligible tooling, barely-there library support, nearly zero users, and a roadmap based on the promise that, after almost fifteen years of working on the "It'll be ready when it's ready!" principle, sufficient volunteer mindset will change to "Let's ship a production-ready release to meet a hard deadline!"
