A nightmare yes, but also why do it? It's more important to optimize for the stock 7MHz 68000, less important on a faster CPU. And most compiler optimizations don't make that much difference anyway.

Old Amiga 68k apps were designed to run on old 68k Amigas, so they hardly need to run faster. Doesn't seem like a good reason to assert that "68k is dead, NG is the future!".
