Superseded by Our Implementation

Reference	Type	Summary	Why Superseded
#1819	PR	Handle unexpected exits in Eventually	Superseded by context-based pollCondition implementation

Under Consideration (Monitoring)

Reference	Type	Summary	Status
#1087	PR	Consistently assertion	🔍 Monitoring - Evaluating usefulness
#1601	Issue	NoFieldIsZero assertion	🔍 Monitoring - Considering implementation

Informational (Not Implemented)

Reference	Type	Summary	Outcome
#1147	Issue	General discussion about generics adoption	ℹ️ Marked “Not Planned” upstream - We implemented our own generics approach (38 functions)
#1308	PR	Comprehensive refactor with generic type parameters	ℹ️ Draft for v2.0.0 upstream - We took a different approach with the same objective
