With the experimental configuration system migration from onExP tag to structured experiment objects, many settings now have mode:'startup' by default. Eg:

'chat.editRequests': {
			tags: ['experimental'],
			experiment: {
				mode: 'startup'
			}
		}

This issue tracks the review of settings that could potentially handle automatic configuration changes when experiment values are updated, and identifies candidates for enabling mode: auto.

Detecting Experiment-Driven Configuration Changes

Components can detect when a configuration change originates because of Default value has update by checking the source property in the configuration change event. When event.source === ConfigurationTarget.DEFAULT.

this.configurationService.onDidChangeConfiguration(event => {
    if (event.source === ConfigurationTarget.DEFAULT && event.affectsConfiguration('your.setting.key')) {
        // This change came from default value change
        // Handle dynamic configuration change
    }
});

Settings Categories to Review:

• Tree Sitter Settings (editorConfigurationSchema.ts) - @alexr00
  • editor.experimental.treeSitterTelemetry
  • editor.experimental.preferTreeSitter.css
  • editor.experimental.preferTreeSitter.typescript
  • editor.experimental.preferTreeSitter.ini
  • editor.experimental.preferTreeSitter.regex
• Inline Suggest Settings (editorOptions.ts) - @hediet
  • editor.inlineSuggest.experimental.suppressInlineSuggestions
  • editor.inlineSuggest.experimental.triggerCommandOnProviderChange
• Quick Suggestions (editorOptions.ts) - @hediet
  • editor.quickSuggestionsDelay
• Layout Settings (workbench.contribution.ts) - @bpasero
  • workbench.secondarySideBar.defaultVisibility
  • workbench.settings.showAISearchToggle
• Chat Experience Settings (chat.contribution.ts) - @roblourens / @isidorn
  • chat.defaultMode
  • chat.emptyChatState.enabled
  • chat.edits2Enabled
  • chat.agent.enabled
  • chat.signInDialogVariant
• Inline Chat Features (inlineChat.ts) - @jrieken / @isidorn
  • inlineChat.enableV2
  • inlineChat.hideOnRequest
• Telemetry Settings (editTelemetry.contribution.ts) @hediet
  • telemetry.editStats.detailed.enabled
• Performance Settings (performance.contribution.ts) @bpasero
  • application.experimental.rendererProfiling

For each setting, evaluate:

1. Can the default setting value change dynamically without causing user experience disruptions?
2. What happens if the setting changes automatically while the application is running?

Next Steps:

1. Component owners review their assigned settings
2. Update autoRefetch: true for settings that can handle dynamic changes
