so I wonder what the benefit is keeping it in the proprietary format at all

yeah my guess was easier editing and ux when collaborating via github, diffs on json don't look great

but yaml (for all it's faults) would still be better haha or now that i think about it:

• https://github.com/hashicorp/hcl
• https://git.sr.ht/~emersion/scfg

both look similar to bru, would share the advantages over json and seem better spec'd/supported
