Yes, you can argue: "that's not fair", "for a professional programmer that's worth only a few weeks of work's for massive productivity improvements", etc., but things don't work that way.

Most developers have been conditioned to not use commercial products, if they can. With an extra downside for the commercial product being closed source.

Fun aside, I once wrote a JVM AOT [0]. Instead of compiling to low level code and building my own GC and runtime, I just transpiled to Go. And it worked, but the Go compiler couldn't handle it well[1] so I started trimming identifier names and shortcutting JRE libs to use Go versions. It became tedious so I gave up. I should revisit that project one day, heh.

That was only one example, and I explicitly mentioned Excelsior instead of other alternatives, because it is free for open source projects.
