If there were indeed anything to be gained by such a feature, it would also need to be implemented on clients. Look around - do any web browsers allow you to isolate CAs like this?
Yes. You can basically isolate CAs into 3 categories (they can interleave): - CAs trusted to issue server certs - CAs trusted to issue email certs - CAs trusted to issue code signing certs
It's utter nonsense.
What is non-sense is having a bag full of CAs for mixed usage. More, you even mix CAs that need to be sent to the client (so it can build a certificate path) with CAs that the server trust (to verify client certs).
