Why promote a default binding before users have,
themselves, actually been binding the command
for a while?

Just because we add a command, and it might be
useful, and it might get used, and users might
bind it, doesn't mean that it needs to have a
default binding.

A fortiori, if users haven't (yet) been binding
it for a while, or if we don't know they have.

The "technical hurdle" of finding a good binding
isn't the place to start.  The place to start is
to wait for users to use and bind it, and then 
see how much a default binding would make sense.
