You have a computer connected to the internet, you obtain a program, and run it.
You don't have to care what it's written in or install a bunch of dev tools, like with Mastodon, where installation docs go on about Node JS, Yarn, Ruby, whatever.
Just provide a binary package. If you can't do that, you picked the wrong tools for the job, IMO.
And of course it's good that it's less wasteful.
I'm running this on the cheapest local VPS that I could find (on renewable energy of course) and I have plenty of headroom.

But I joined the chat rooms and might send some patches in the future. If you want to try, I believe Golang is quite easy to pick up.. especially compared to Rust (I'm assuming you know Rust).
