It's supported in clang as well per the documentation [0] in at least some
configurations or distributions:
"The [[maybe_unused]] (or __attribute__((unused))) attribute can be
used to silence such diagnostics when the entity cannot be removed.
For instance, a local variable may exist solely for use in an assert()
statement, which makes the local variable unused when NDEBUG is
defined."
[[maybe_unused]] is also recognized from Visual Studio 2017 onwards [1].
