It's not annoying, it's what dedication is for.  It's not more annoying 
than using C-x C-q in a buffer, and later typing something in that buffer 
and realizing (with a similar error message) that it doesn't work: you get 
what you asked.

If you think that's annoying, then I'd suggest setting the 
switch-to-buffer-in-dedicated-window configuration option.  It's there for 
a reason, and you can select between no less than four behaviors: one of 
them is likely the one you want.

I don't know which "others" you have in mind, I do recall that some 
disagreed (is there a single topic on emacs-devel on which no one 
disagrees?), but IIRC at least Lars said that it would be nice to have a 
full repertoire of commands to manage windows under C-x w.

I'm fine with that, too.
