> Take integers for example. In java they're defined to be 2s compliment; the processor architecture doesn't matter. C/C++ left the spec open to let the language be 1 to 1 with the medium, Java did not.

There is a historical reason for this. In the early 1970s, when C was first designed, non-twos complement machines (such as CDC and UNIVAC machines) were still an important part of the industry and so it made sense for C to be designed to allow supporting those machines. By the 1990s, when Java was designed, non-twos complement machines were much less relevant, so it made sense to exclude support for them from the design of Java. Now finally, in the late 2010s, when the relevance of those machines has shrunk even further (although ones-complement Unisys mainframes still exist even today), it makes sense to remove that support from the C standard, even though it made a lot of sense when C was first designed.
