Let's get real here.  That entire section refers to batteries being 
charged while in use so none of what you're saying is relevant.

I operated QRP battery operated in Field Day for many, many years, 
charging the battery from the AC mains before the event and charging it 
during the event from a small solar panel.  I typically submitted a 
detailed description of that entire process (complete with pictures of 
the solar panel in action) and never got a sliver of feedback that 
anything I did was improper.  In 2000 K7ZB and I even set what was then 
the all-time record for 1B-2op Battery with 10,000 points, so I assume 
that our entry would have gotten at least a bit of scrutiny.

I see no value in extrapolating such things to the ridiculous.
