 [^erase]: It is of course still possible to erase provenance during compilation, *if* the target that we are compiling to does not actually do the access checks that the abstract machine does. What is not safe is having a language operation that strips provenance, and inserting that in arbitrary places in the program.

+*Historical note:* The author assumes that provenance in C was originally intended to be purely descriptive.
+However, the moment compilers started doing optimizations that exploit undefined behavior depending on the provenance of a pointer, provenance of de-facto-C became prescriptive.
 A lot of the confusion around provenance arises from the fact that many people still think it is purely descriptive.
+The standard has never been updated to clarify this, but in 2022 the committee has accepted a Technical Specification that does explicitly state that C has prescriptive provenance.
 The point of this RFC is that Rust has *prescriptive* provenance.
