This is another rule that really makes no sense. But, it is a rule.

Actually, it makes a lot of sense. If you put a motor on the Spike and it pulls too much current under load, the fuse will blow, end of story.
If you have a reset breaker in there, it will snap, reset, snap again, reset, over and over again, not providing proper circuit protection and causing something else more important to become the fuse, sometimes with frightening consequences.
The use of the resetting breaker in the compressor is a concession suggested by, I believe, the manufacturer of the compressor. It has a high in-rush current on startup, but a much lower running current. Other motors don't have that characteristic.
