I'd argue that nowadays a pre-1.0 version number usually means "this doesn't have all the features I want it to have yet" more often than "this is buggy and shouldn't be used in production yet," at least nowadays. I can't speak for Bun but I know Zig has an extensive test and timing suite to help avoid bugs or significant slow-downs making it into new releases.
As for who's using Bun in production, I don't know. But it's been around for a while and seems to have decent buzz around it in the JS community when observed from a safe distance (the proper way to observe the JS community), so I assume someone is. Take that for what it's worth.
