Logview needs to temporarily cancel restrictions in _practically all_ its function.
It can do so (or more precisely will be able to do so) by calling narrowing-unlock with the appropriate tag, which IIUC correctly is, in your case, 'fontification-functions. I don't see why you would need anything else, especially given that a general mechanism to disable locked narrowing everywhere is already available for users who, like you, don't care about long lines.
