I'm a Gentoo user myself so from a personal perspective I don't see any problem, but in a professional environment it's another thing I have to do - Install (and update) Go from somewhere because it's obviously not in the CentOS repositories (at least in an acceptable version), set up a build process and make sure to build updated versions, etc. Just dropping in libraries into some directory to be loaded as plugin would be arguably easier and is kinda "standard" for plugin systems.
