I recently started some work trying to clarify the non-integral pointer semantics. Right now we assume non-integral pointers are both numerically unstable (e.g. copying GC) as well as not just an address. I'd like to split these two properties (Draft PR https://github.com/llvm/llvm-project/pull/105735) and then we'd be able to restrict this to unstable pointers while still allowing it for fat pointers and/or CHERI capabilities.
