This costs money. A lot of money. Last I checked, a complete Amiga cost
less than a single 68030. When you're already making heavy use of a silicon
foundry to cut your parts count...

Besides, I said "you have to add more processors". Not "you have to add special
purpose CPUs". People have been using 68000s and other CPUs as I/O processors
for years.
