If location_wrapper_p etc. are in generic code rather than only in the FE,
sure, you'd need to use some generic flag rather than FE specific.
I bet e.g. private_flag and protected_flag aren't used yet for
VIEW_CONVERT_EXPR/NON_LVALUE_EXPR, but they are used on some other
expressions, e.g. CALL_EXPR, which suggests that it could be used for that.
