I want to comment that I've heard people say that too, but I think it
is, well, over optimistic.  When weird addressing modes are in play, I
believe that LEGITIMIZE_RELOAD_ADDRESS is currently required to handle
them.  The alternative is to teach reload about all possibilities for
all chips, and that does not make sense to me.
