I guess that is John's point. He sees attics where there is no crawling involved. You can walk up to the panel normally.
It would have to be that way to get my OK.
I did allow some attic mounted panels in the Ringling (the circus people) mansion but it was air conditioned space with a 7-8 foot ceiling. I still made them add a better access ladder (permanently mounted) and closer to the panel than the existing one which did require crawling over mechanicals to get to it.
