LGTM. I'd recommend staging the removal. We need to get into the habit of not changing application and configuration and expect them to be in perfect sync always.

Up to you if you want to tackle the comments, but I'd recommend it.

FWIW, I'd recommend renaming this to _ to make it unused in the first phase of removal. Config can be really nasty and sometimes you've got old versions of config that do define this field. We'll fail to parse the json/yaml when there are fields which are not defined in the struct.

got old versions of config that do define this field

Two comments on this:

• this is the versions file. We don't use it as config, plus no-one should do so
• if this were a relevant config field: instead of manually managing obsolescence of single fields, which involves multiple PRs, managing phase-out periods and such, we should instead make our parsing behavior in installer less picky (e.g., with a "warn but continue anyway" flag). The current hard lock-in between a) installer binary, b) versions file and c) config is not flexible enough for RL usecases.

We should be cautious where it make sense, but also watch out for our pace. 🙂
