Only among contributors not considering non-8-bit bytes. SImode is 4

I think you just described the majority of contributors. :-)
It's human nature not to recognize one's tacit assumptions or their
consequences. It's also normal for people to focus on what they are
working on and pay far less attention to other targets. Since there
is no working and supported 32-bit word-addressed target, there's
little to alert anyone that one of their assumptions is not valid.
It may be that my current problem is limited to unwind-dw2.c.
If so, then I may be able to work around it by simply not building it.
