Because we've got 100+ studied and defined architectural patterns. And 2000+ studied and defined other patterns.

Who benefits from the numbers if nobody remembers all those patterns? And they cannot be remembered because there are too many of them. And there are too many of them because they are not well-organized, thus the same thing is reinvented or rebranded again and again.

I intend to make a classification of patterns to highlight duplicates and arrange the already known information, just as you do with classes in OOP - you don't write a new class from scratch if you see that 90% of its functionality is already available - you inherit. Why do we never inherit patterns?
