"and any non-zero value will be True when unpacking" from the docs,
which does not seem to make any sense for _Bool.

I disagree. I don't think struct module's job is to be faithful to _Bool semantics.

Up to this point, "?" worked for bytes with "only 0 is false" semantics, in a reliable and documented way. I don't see a reason to let that continue.

You're right about trap representations, but IMO floats are much more tied to hardware (and serious users of float are aware of the pitfalls), while _Bool semantics are governed by the whims of the compiler.

Also, the "@" prefix is specifically documented to select native Byte order, Size, and Alignment; not how the bit-pattern is interpreted.
