@mborzecki I read your topic on arch-general last night. I used to be an Arch Linux TU. I have to tell you that, it is the Arch way 
Allan McRae has advocated for getting more TUs into the project that maintain few packages in the past. If you’re interested, I’d suggest you apply to become a TU. For that you will need to be sponsored by an existing TU. I can help recommend someone if you want to pursue this.
Many Arch users are installing Arch via Antergos these days and many more have switched to Manjaro. Antergos have a small repository carrying some packages specific to their needs while Manjaro have their own repositories. We’ve had good engagement from @philm at Manjaro in the past and Antergos showed some interest. Perhaps working with Manjaro and Antergos would help bring snapd to a large “Arch Linux” user base?
Let me know you thoughts, I can help with introductions
