Here is a question that would seem to have a lot of opinions for answers. Are questions like this ok?

It's asking about what commands is ex mode are actually useful.

Does Ex mode have any practical use?

A "what commands are useful"-question is a very opinion-based question. Some might consider command 'foo' to be very useful, but the next might consider it to be stupid.
This would quickly spark a discussion. While this discussion might be interesting, it's not a good fit for the SE format in general. I don't see why vi.SE should be an exception.

However, the question you link to, doesn't ask "what commands are useful", as I read it, it asks "What is Ex mode, and how is it useful?". This is a different sort of question that can be answered objectively.

    Yep, that's exactly what I meant! I was a little doubtful when asking the Q myself for precisely this reason, but decided in the end it did fit the criteria of being objectively answerable. Feb 5 '15 at 23:29
