Yes, there are indeed some. A common one is (eq \, (car-safe EXPR)) to
test whether some expression is an "unquote expression". Used in
code-walker like things - byte compiler, stuff to save expressions in
files, pcase, such things.
Any package can make use of the reader constructs in non-trivial ways (I
mean, uses unrelated to backquote). And the only way to treat such
expressions is to test for the expansion.

See my other comment then.
