But otherwise this seems like a good idea.  We do potentially have
clobbering definitions -- where there is a

(put 'narrow-to-region 'disabled nil)

in the buffer, and then it's also customised...

But I don't really think this is much of a problem in practice.

If that defcustom form works, then I'm all for changing over the
enabled-command stuff to customise.
