Just to note that I think it is very important for debugging purposes to be able to turn the warning on.

In fact, it can be turned on, but it produces no effect...

Yes, that's how I found that 'bug'.

I really like that feature, but sometimes it hides bugs. So it would be helpful to be able to turn off automatic broadcasting to find mismatched dimensionalities.

Thanks for the bug report, Max.  I recently tried arguing that the old behaviour should be reinstated, which I think is the best way for the documentation to match the behaviour :)

Would you like to be able still to run  warning ("error", "Octave:broadcast")?

the documentation section 19.2.1 says:

To disable this warning, refer to its ID (see warning_ids):

warning ("off", "Octave:broadcast");

If you want to recover the old behavior and produce an error, turn this warning into an error:

warning ("error", "Octave:broadcast");

However, section 12.2.1 does not list the ID "Octave:broadcast", and furthermore, the examples don't work.
