We do have the same level of verbosity in Panthor, and it's proven
useful when people are filling bug reports. Asking them to reload
the module with debug prints enabled is kinda annoying, and I don't
think I've heard anyone complaining that this was too verbose or slowing
down the boot, so I'd be tempted to keep it like that, and least for
the information printed in this function.
