The problem with the symbol property name `repeat-exit-function` is that
the existing variable `repeat-exit-function` has another purpose.
For example, for `repeat-exit-timeout` there is the global variable
and the symbol property with the same names because they are doing
the same thing.
But the variable `repeat-exit-function` is different. It's not
customizable by the user. So another name would be preferable.

Indeed, before adding a new symbol property could you please try to use
the existing `repeat-echo-function`. It's called with the nil argument
on exit. Do you need a symbol property `repeat-echo-function`, or can use
the global variable, e.g. by checking some buffer-local variable in it?
