> Personally, I like 3.1.2 from your link [0] best, which involves getting rid of pointer <=> integer casts entirely, and just adding methods to pointers, like addr and with_addr. This needs no new types and no new syntax, though it does make pointer arithmetic a little more cumbersome. However, it also makes it much clearer that pointers have provenance.

Provenance-related work seems to be progressing at a decent pace, with some provenance-related APIs stabilized in Rust 1.84 [0, 1].
