[Exploratory] Dynamic user registration controls

[heysamtexas]

Description

EXPLORATORY TICKET - Research dynamic control over user registration and signup process through django-allauth.

⚠️ Complexity Warning: Registration controls affect user onboarding flow and may require custom adapter implementations.

Current State

Registration settings hardcoded in settings.py:

• SOCIALACCOUNT_AUTO_SIGNUP = True
• Various ACCOUNT_SIGNUP_* settings

Research Goals

• Investigate dynamic signup form field requirements
• Test social account auto-signup toggle capability
• Research custom adapter override complexity
• Document impact on existing social connections

Potential Areas to Explore

1. Signup Field Requirements: Dynamic required/optional fields
2. Social Auto-Signup: Toggle automatic account creation
3. Registration Open/Closed: Site-wide registration control
4. Approval Workflows: Admin approval before activation

Implementation Complexity Assessment

• Low: Simple boolean toggles (registration open/closed)
• Medium: Social account behavior changes
• High: Dynamic form field requirements
• Very High: Custom approval workflows

Decision Framework

Only pursue if:

• ✅ Clear admin benefit identified
• ✅ Low-complexity implementation path exists
• ✅ No impact on existing user flows
• ✅ Minimal performance overhead
