It's not the same -- giving them the ability to recover is better.  :-)
We're teaching users to hit "y" after a whole bunch of commands, and the
"y" becomes automatic.

It does, but a thing like this doesn't have to be 100% to be useful.
Every new thing that's made undoable is progress.

There isn't, but if it's worth having a query, then that query is worth
the most to new users -- more experienced users can then choose to
switch it off or on.  Adding this option, but defaulting it to nil
doesn't add much value, in my opinion.  Anybody can add a prompter to
any command by just doing:

(advice-add 'bookmark-bmenu-execute-deletions :before
            (lambda () (unless (y-or-n-p "Really execute?") (error "Nope"))))

Perhaps we should just make a convenience function for people to add
prompters to any command they want to...
