I disagree with this, if you start going above and beyond on your work consistently people/co-workers/the company will get used to this and it becomes your baseline. Why pay more for someone already doing the work?
Achieving above your pay grade for a long period can also place you in the tricky situation of management agreeing to a raise if you up X/Y/Z, if you're already performing to a high level without monetary recognition then you're in a tough spot.
All this leads into why lots of engineers struggle to get raises within the same company and then with a few career hops will instead double/triple their salary.
The cost of the lost productivity from domain knowledge within companies leaving with engineers who can't get raises must be far higher, especially as going out into the current hiring market means you'll probably have to pay equal or more for a similarly skilled but without domain knowledge engineer.
