The wrapping APIs do come up a lot in cryptography, but in bit twiddling I think they're as often a hindrance because we actually want to be pulled up short if we're trying to squeeze things where they won't fit.

It have definitely written C code which tries to use 257 values for a byte, with zero playing both its role as "just zero" in some places, and then also serving as 256 because "it's never zero" in other places and of course this is a nasty bug if one of those "it's never zero" zeroes gets into the "it's just zero of course" code paths or vice versa.

The "Wrapping will fix my arithmetic ordering" thing is in this article too and I think that's also a terrible idea, maybe even worse than the wrapping unsigned integer types themselves because it leads to a muddled idea of what's really going on.
