Does anyone know of a good reason why Emacs's .BAK and .CKP files
should be mode 0600 all the time, instead of the same mode as the
original file?

    A probable reason is to prevent other users from clobberring your .BAK
and .CKP files when:
(1) they will be/are working in the same directory as you are,  and/or
(2) they are editing the files that you edited earlier.
    Of course it also means that they probably won't have their .CKP and .BAK
files.
