-// RE2 has two versions: "sans Abseil" in the main branch; and "avec Abseil" in
-// the abseil branch. This has led to a diamond dependency problem for projects
-// like Envoy: as per https://github.com/google/re2/issues/388, GoogleTest took
-// a dependency on RE2 avec Abseil, but other things depend on RE2 sans Abseil.
-// To resolve this conflict until both versions can migrate to std::string_view
-// (C++17), those other things must be able to #include "re2/stringpiece.h" and
-// use re2::StringPiece. (This is a hack, obviously, but it beats telling every
-// project in this situation that they have to perform source transformations.)
+// Until RE2 requires C++17 and uses std::string_view, allow users to
+// continue to #include "re2/stringpiece.h" and use re2::StringPiece.
