I can't seem to find any situation where it performs worse. Hence my question on whether it's a better idea to condition this behavior on a Kconfig option rather than a DT blob which may or may not be in sync.
If it's unconditionally worse then it shouldn't even be a Kconfig option, just make the driver just never use the interrupt.
