Currently guarded regions on Windows are represented as a Region, where protection is equal to the guarded region's underlying protection, and guarded set to true.

This might be confusing, since library users may only check for protection & Protection::READ or is_readable(), and thereafter assume the memory region is accessible.

Is it more ergonomic to discard the underlying protection of guarded pages, and merely set protection to Protection::NONE whilst also retaining the guarded boolean flag?

This would mean that information is lost, but would most likely result in fewer surprises for the user.
