Seriously, nearly everything else in the game has a "Are you sure?" prompt that forces you to answer Yes/No, except for the ONE thing I really wish had it, and that's the /logout and /shutdown commands.
I don't know how many times I do crafting on multiple mules (such as "Jinx") and I log a mule on after doing a previous mule, do, say a bone hairpin and then hit Up then Enter to recall last command (because /lastsynth is a habit now)....
Whoops.
Last command was /logout. *sigh* So I gotta waste time logging back in, and doubly so if I happened to be in my Mog Garden which takes MUCH longer to load than the Mog House does.
So please.... Yes/No confirmation prompts on /logout and /shutdown please.
