Exactly this! One day I was complaining about the standard tile layer, and then @Minh_Nguyen made an off-hand comment about OSM US wanting to make an American style “some day”, and then in a heartbeat later I rage-created the OSM Americana map style.
Proofs of concepts are not expensive. I ran a global map style with continuous rendering in the cloud for “coffee cups per month” budgets, out of pocket. Once I figured out all the nuts and bolts, OSM US happily partnered with our team and now they pay the “coffee cups per month” budget for serving tiles. That’s what stepping up looks like in a decentralized project.
What I believe @SomeoneElse is suggesting, is to just do it, then show it working, even if you’ve gotta spend a couple bucks to set up a cloud services account somewhere. If OWG had to take the time to entertain every random well-meaning comment or suggestion about how they were doing things wrong, they’d never have time for server administration as I’m sure you can imagine. Stand up a working prototype that solves real problems? I think that’s something we’re all very interested in.
