Isn't that the whole promise of general purpose computing? That you don't need to find specialized hardware for most workloads? Nobody wants to be out shopping

Isn't that the whole promise of general purpose computing? That you don't need to find specialized hardware for most workloads? Nobody wants to be out shopping for CPUs that have features that align particularly well with their use case, then switching to different CPUs when they need to release an update or some customer comes along with data that runs less efficiently with the algorithms as written. Since processors are expensive and hard to change, they do tricks to allow themselves to be used more efficiently in common cases. That seems like a reasonable behavior to me.
