Feature detection is better than version detection…??? Maybe for the web but jn compiled language world This has led to autoconf automake which is a gigantic waist and also a gigantic waste. Rust style cargo library version specification solves so many problems that are obvious…. We want to comple and link with the exact same version of library code that we built and tested on , because you cannot possibly test every feature nor can you test bug compatibility. This increases portability , not decreases, meanwhile C programs are not even portable between different versions of linux due to library issues. Im skeptical of some of these ideas.

The most successful thinwaist of all is VBA and Excel which of course are never mentioned .
