What would you like Renovate to be able to do?

Deprecate use of extends in global config and replace with globalPresets and repoPresets. Current extends behavior will map to repoPresets while new optional globalPresets will mean the preset is resolved during global config resolution, not repo config resolution.

If you have any ideas on how this should be implemented, please tell us here.

• Note in extends that it is for repo config only and to use the others for global
• If found in global, migrate it to repoPresets and WARN
• ignorePresets in global config apply only to globalPresets
• Document the differences well, e.g. repoPresets are passed through to repo config so can only be overridden by repo config including ignorePresets. globalPresets are resolved during global config resolution and so cannot be ignored by repo config directly

Is this a feature you are interested in implementing yourself?

No
