I think the motive is quite clear but perhaps it would be too inconvenient.
At the moment Gnus and Edebug use the global value for overlay-arrow-position
which presumably makes debugging Gnus with Edebug a bit awkward.

FWIW using overlay-arrow-position as a local variable, like compile does,
means that the overlay-arrow-string is not visible on text-only terminals.
