Indeed.

Music functions are defined in a simpler way: they take a fixed number
of arguments, and by convention music is always in the last arguments,
so \afterGrace invocation should look something like

\afterGrace #'(15 . 16) d1 {c16[ d] }

You could still have the same behavior as before (including its
disavantages) with

#(define afterGraceFraction (cons 15 16))
%% ... lots of music input ...
\afterGrace #afterGraceFraction d1 {c16[ d] }
