Status: OUT
Python's language-level defaults are a primary determinant of the convergence landscape: they privilege streaming by making it self-sufficient (Counter's zero-default, set's O(1) membership, arbitrary-precision integers require no external infrastructure), and this self-sufficiency aligns with the adoption-barrier gradient that makes convergence strength predictable from prerequisite count — suggesting the convergence pattern is substantially shaped by the host language's built-in semantics, not solely by the problem domain.
Strategy privilege (which strategy is dominant) and the adoption barrier gradient (why convergence strength varies) are both downstream of Python's defaults — combining them shows the entire convergence landscape is language-determined.
