Australia/Malaysia/China and Italy/Singapore/Japan all on one engine are good enough reasons.
After Malaysia and Italy respectively the engine would be very tired. The teams would lose a lot less re-using it somewhere like Monaco or Hungary and not having it expire in a cloud of smoke at another high usage circuit.
A subtle rule rewrite is more sensible than changing the calendar.
