Indeed.  We were never discussing `lock-buffer', this is all about
`emacs-lock-mode'.

It is also already taken to set the "locking mode"... ;-)

I would not, this would be too distracting.  Using the prefix arg of
the mode function, or a function in the mode hook that would
prompt automatically would be better.

But I still think the feature is useful in general.  When I'm getting
distracted by some other stuff, I want to know why I had locked that
buffer that prevents me from exiting.

I'm testing master for a long time now so I don't rely on locking
currently.  Locks don't survive crashes.

People don't use it because it's not really cool.
