For one, it's completely non-obvious from the name. We could introduce a new variable named `inhibit-auto-save-session' that would do exactly what its named implied. In addition to better clarity, the advantage would be that the auto-save code could always recover from a change of that variable in the middle of operation, because changing it does not destroy any actual information. For compatibility with the FSF and for sanity, we could also make setting auto-save-list-file-prefix to nil have the same effect. The warning would then not be necessary because you're not supposed to do that anyway. Yoshiki, Troy, what do you think?
