Why:
The original idea with this pattern is to try to avoid unnecessary renders of context consumers, where object context values would always be strictly unequal between renders unless memoized (
{} !== {}). However, when trying to find some resources justifying the pattern, I found more resources in favor of avoiding "premature" memoization, or finding alternative ways to reduce re-renders ([1][2][3]). That being said, I still think there is some value in the memoization, and at least the first two points of the list above provide value for existing usage.
