For one, loplugin:unusedvariablecheck does not merely check for unused variables with types from the standard library since fe216494 "teach unusedvariablecheck plugin about SfxPoolItem subclasses", so disabling loplugin:unusedvariablecheck based on HAVE_GCC_ATTRIBUTE_WARN_UNUSED_STL is wrong. For another, I have seen no standard library implementation that decorates its types with such "warn-if-unused" attributes, and <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0600r0.pdf> "[[nodiscard]] in the Library" (which proposes to add the corresponding C++17 attribute to just a few select functions and no types at all) makes it appear unlikely that will happen.
