We do for UTF-8, btw. See unicode-error-sequence-regexp-range,
unicode-error-default-translation-table, #'unicode-error-translate-region. 

Yes, it might be nice to extend this to support non-Unicode coding systems. 
GNU’s unibyte vs. multibyte concept is similar, but about a thousand times
morea pain in the arse to work with than our current architecture, and
conceptually not any less ugly.

One more thing that’s slightly depressing for me; if you open
lisp/mule/greek.elc as binary (the default, for other, broken, reasons) the
buffer is trucated. That shouldn’t have happened.
