can/should the rel/ directory be checked into git?

Hey team,

I’m new-ish to Phoenix (v1.6, LiveView 0.17) and really enjoying it so far.

I’m deploying to fly.io according to the online guides. One thing that happens (as part of the release step) is that there’s a rel/ directory created, which in my case includes:

env.bat.eex
env.sh.eex
remote.vm.args.eex
vm.args.eex

It’s all working well, however my question is about whether I should check these files into git or not. There’s some config-y stuff in there, but nothing secret afaict (and the release mix task doesn’t add rel/ to .gitignore or anything, so it seems like it’d be ok (and even good) to check it in. But it doesn’t seem to be mentioned in the guide, so I thought I’d check what others are doing.
