Only thing it does, is make UTF-8 terminals work exactly same as non-UTF-8 terminals, instead of beaing broken But UTF-8 is not the only encoding that uses the 8th bit. So this must be a separate setting, unrelated to the encoding being UTF-8 or not. What you want is for Emacs to interpret the 8th bit after decoding characters and not before it as it does now. So I think a new non-nil value of input-meta-mode should be introduced to trigger this behavior, and you should drop the tests of the encoding being UTF-8, as it's not the only encoding that can be affected.
