First things first, let me tell you that we do have a devportal open to all our partners, not only for those who are implementing Galaxy features. Within this portal every developer can get a hold of our build delivery tool that works exactly like steampipe - updating a game on GOG is a matter of executing a single script.
Just to be on the same side, not every partner has switched to this system, but the ones who did are in the grand majority, and we are strongly encouraging all partners to use it.
Apart from the tools, documentation and dedicated Product Manager, each partner has an entire dedicated support team at their disposal.
What's more, after the build gets published on GOG via devportal, we test every single one of it - the reason for that is that we want to able to provide our developers with feedback regarding their games to maintain the quality of our products.

Hope this will one and for all clear things up regarding the build delivery system on GOG. Just remember, how the developer provides builds to GOG depends on many factors, however the final decision is always up to them.
