I don't think that #(+ %1 %2) is very difficult to learn.  So I don't
see a significant downside in supporting this construct.

On the other hand, for that particular function, you could write '+.

But the answer is simple: they are equivalent, the choice is a matter
of taste.

That is not much of a simplification, and think it is a drawback
to display different text from what is really in the file.
#(f % 1) avoids that drawback.
