The use of 'strictly' notes a lack of exception, as in Aedilred's examples. But it also implies the existence of 'leniently forbidden', which may simply be the more general 'forbidden' with implicit exception from liability.

I like to use "I could care less," especially around those who I know would feel inclined to call me on it, so that I can just as snootily correct them with, "no, I literally could care less, but the default scale is from one to ten. By default, my level of concern must be recorded at 1, though in truth, it is, in fact, zero. I don't even care enough to bother specifying the more accurate scale. But I could."
