That backquote change made `read' signal errors when reading
subexpressions of otherwise valid code.

The change under discussion changes what is valid code, so you won't
have the problem of getting read errors for valid code.
(changing what is valid Lisp has other drawbacks, as Drew has
repeatedly pointed out)
