As shown here:

https://github.com/cplusplus/papers/issues/1489

these are presentation slides for P2188R1, whose status
is shown here:

https://github.com/cplusplus/papers/issues/895

The actual paper is here:
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2020/p2188r0.html

Note the last comment in the github issue:

"guidance was given to the authors, and we expect to see an omnibus solution to the problem, based on #1364."

and #1364 is

P2434R0 Nondeterministic pointer provenance (S. Davis Herring)
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p2434r0.html

That doesn't sound like an approach is being pursued that would
disable most pointer-related optimizations.
