I venture to suggest, spoken from the perspective of a few decades experience, managing high and low values in-camera e.g. nailing the exposure so that scanning using ordinary, uncomplicated settings is for the most part, troublefree. Leaving the task of manipulating a B&W print to an automated scanner program or plug-in might even make the situation worse by imparting a discernible 'digital fakery', for want of a more succinct term.
The scanning process is inherently imperfect and, if skill and experience is lacking, is prone to creating strife as an altered digital representation of a physical print. Realism must be retained and expressed in the resulting image to the viewer.
Automation is something that bugs me. I fear that in the not too distant future anything to do with scanning is going to be gleefully hijacked by the reach and advance of AI, with progressively less control from the hitherto none-the-wiser user.
