• Do we anticipate that there will be any changes to how we deploy in dev after this PR is merged?
• The changes look fine with me, just not sure what the effect of this will be for us

@ra0x3 the current dev environment is not affected. I didn't touch the current configuration. This applies only for the new infrastructure setup, where we deploy via Flux, as we discussed in our meeting last week.
