Quick rant: why isn't there an Exception(string, params object[]) constructor?

This Stack Overflow question has reminded me of something I often wish existed in common exception constructors - an overload taking a format string and values. For instance, it would be really nice to be able to write:

Of course, with no way of explicitly inheriting constructors (which I almost always want for exceptions, and almost never want for anything else) it would mean yet another overload to copy and paste from another exception, but the times when I've actually written it in my own exceptions it's been hugely handy, particularly for tricky cases where you've got a lot of data to include in the message. (You'd also want an overload taking a nested exception first as well, adding to the baggage...)
