This feature only exists as a mechanism to suppress the warning introduced in https://github.com/swiftlang/swift/pull/75378. The RegexParser module, which is effectively part of the standard library, declares a Swift runtime symbol and as a result every build of the compiler and stdlib produces warnings which there are no plans to address. Warnings that are not going to be addressed need some way of being suppressed, and an experimental features seems like a reasonable mechanism for this one.
