I agree with your opinion, but I'm not surprised that Wikia Staff disagree. ;)

I vaguely recall some other button to collapse the right rail entirely also not being allowed site-wide.

It seems like buttons which change the interface are generally not allowed, even if the default state is... the default state. The line appears to be drawn so that the user has to actively edit their own JS/CSS in order to change the look. This is probably because not many people will actually take this extra step, and Wikia Staff don't want to make it too easy.

The best you can do is highlight a thread with easy to follow instructions, for the few people who will take the extra step.
