The evils of cross chaining are exaggerated.
Assuming the RD has the capacity and the chain is the right length, no great harm will come of cross-chaining. Certainly the middle ring should be usable with the entire cassette, otherwise 1
setups wouldn't exist.
Though it isn't sudden death, riding crossed over is less efficient and causes extra drive train friction and wear. It's a matter of degree, with the most crossed being the worst. But riding crossed may make sense from time to time in certain situations, such as topping a grade and needing one more downshift, yet not enough to shift the front.
The other problem with cross chaining on certain bikes is that it might make FD trim issues, or the chain may rub the larger chainring on small/small combinations.
An ounce of diagnosis is worth a pound of cure.
