That is not a solution because it means the code can behave differently, and expose vulnerability if wrong compilation settings are chosen.
The functions like "wrapping_add" have such a long names so that nobody wants to use them and they make the code ugly. Instead, "+" should be used for addition with exceptions, and something like "wrap+" or "<+>" or "[+]" used for wrapping addition.
That's how people work, they will choose the laziest path (the simplest function name) and this is why you should use "+" for safer, non-wrapping addition and make the symbol for wrapping addition long and unattractive. Make writing unsafe code harder. This is just basic psychology.
C has the same problem, they have functions checking for overflow, but they also have long and ugly names that discourage their use.
> modern hardware will just wrap if you don't check and that's cheaper
So you suggest that because x86 is a poorly designed architecture, we should adapt programing languages to its poor design? x86 will be gone sooner or later anyway.
Also, there are languages like JS, Python, Swift which chose the right path, it is only C and Rust developers who seem to be backwards.

If the software is correct nothing changes. The existence of people who write nonsense but expect you to work around that doesn't change between languages, they write crap in Swift or Python or Javascript just the same.
The long names are because there are, in fact, a lot of things you might want. Although Swift manages to take several pages and lots of diagrams to explain what wrapping is, that is in fact all their special operators do. What if you don't want wrapping? Too bad.
Rust provides saturating, which is almost always what you wanted for signal processing (e.g. audio) as well as separate "carry" booleans to do arithmetic the way you were probably shown in primary school, the wrapping most often provided on hardware and useful in cryptography among other places and explicitly cheap but dangerous and expensive but safe options. It also provides both kinds of division (and remainder), which doesn't matter for the unsigned integers but is important for signed integers and is a source of confusion and woe when languages provide only one kind or worse a mixture that makes no mathematical sense. These all need names.
