Not sure - if we can do the handling above then sure we could make that change.
I can see there is a path to register the callbacks but I'd kind of assumed

I think "romd" means "read mostly".
In the case of flash, I believe that a write changes modes (block erase something
something) and the region changes state into MMIO. But normal state is read mode where
read+execute go through unchallenged.
It has been a long time since I studied how all that works, so I may well have forgotten
something.
