Is the idea behind this that you can run some active code to remove the features? I can see that.
I've considered a generic framework in foreman, like foreman-rake plugin:remove[$plugin]. This could be used for it.

Overall I like the structure/concept.
Probably not a blocker, but today we can easily remove Foreman Proxy features. So we can easily remove smart_proxy_ansible, but not foreman_ansible. I know you didn't mark it as removable now so we can deal with that in the future.

Okay, prod-only is fine for now as long as you promise to think about devs ;)

Do not reject an absent feature as a removed dependency.
If registration is enabled and templates is absent from the persisted user list, --remove-feature templates changes nothing. Line 172 still adds templates to remove_set, and the dependency check rejects the deployment. registration declares templates as a dependency, so this breaks the documented idempotent no-op. Track which entries the remove action actually deleted, or compare against the prior explicit feature list before checking dependencies. (github.com)

Restore the initial bmc deployment state on cleanup.
When bmc was initially enabled and a post-removal assertion fails, the cleanup branch performs no deploy. The finally block only restores parameters.yaml, so later tests in the same CI environment can observe bmc as removed through ./foremanctl features. This is a failure-path test-environment leak, so the severity is minor.
Suggested fix
- if not initially_enabled:
- cleanup_result = _deploy('--remove-feature', 'bmc')
- assert cleanup_result.returncode == 0, cleanup_result.stderr
+ cleanup_argument = '--add-feature' if initially_enabled else '--remove-feature'
+ cleanup_result = _deploy(cleanup_argument, 'bmc')
+ assert cleanup_result.returncode == 0, cleanup_result.stderr📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Why are you introducing these changes? (Problem description, related links)
--remove-featurecurrently edits the persisted user feature list, but removal requests need validation before they can safely change deployment state. In particular, users must not remove unknown or non-removable features, flavor-provided features, or dependencies still required by enabled features. This depends on the pending Obsah PR #140, which exposes raw removal operands to playbooks without persisting them.What are the changes introduced in this pull request?
removablemetadata for BMC, Templates, and Registration, and show removability inforemanctl features.featuresas the single persisted user feature list; use transient removal operands for validation and validate feature changes inpull-imagesas well as deployment playbooks.How to test this pull request
