This is the case where it defaults to localhost when its missing?

The host is actually required, but it was to fix #34954 until we remove this function to check _macs_already_configured as agrred here #34888 (comment)

Needed stuffs to get the MAC addresses are on 0.8.0 and updated in this PR #35068, and throught this was a breaking change.

But if you correct the MAC addresses, we actually don't need this PR.

(I hope I made myself clear 😄)

I converted this to a draft so it doesn't merge as we should probably fix the duplicate discovery issue instead

Ok, 0.8.0 adds dsm_api.network.macs to do so 😉
