What are examples of when you want this behavior, that aren't handled
as easily with the current spec?

What are some examples of things Closure needs to do with blockquotes
that aren't easily supported by the current spec?  (indent/outdent is
intended to be the way to change blockquote level, not formatBlock.)

That's debatable.  In any event, I'd like to hear concrete use-cases
before changing the spec.  Real-world experience is valuable, but it's
also often based on having to work around browser bugs, which isn't as
important when writing a spec.  E.g., if you're using formatBlock to
handle blockquote because some browsers don't support indent/outdent
the way you want, but indent/outdent as specced will work fine for
your use-case, that's not a reason to change the spec.
