That is a fair request, but brings with it a lot of complexity. It isn't sufficient to have a libgo.so, but one that very closely matches the one that the tools were built against. Considering that libgo.so contains all the important parts of the standard library like crypto, compression, http, json, reflection, etc. We also need to ensure that whatever tools we are deploying, are running with an up to date libgo.so. In short, libgo.so and the tools need to be distributed together -- or -- the tools need to control the version of libgo that is installed on the system. This would be easier to accomplish if the tools were packaged as a deb. But that come with other complications for things like upgrades.
