Yes, but the manager with a shitty MBA doesn’t care about overall company appearance of performance, as long as their department looks good on paper. And they figured that would be easier by using four different external libraries, and then let another department figure out the rest.
In some cases they’re testing/training for the most common solutions human use for a problem with multiple paths and choices.
It’s part of trying to make them seem more human-like and as if they have general intelligence. And not just give the optimal and computer calculated solution, or the solution one or a few programmers think is the common solution. It needs data.
And if it’s one of those who actually check, but has multiple paths, do the convoluted one(or just refresh).
