A @warningonuse("some text") used for editors is just a convention, it needs no language changes.
All compiler-hints are conventions: @assert(), @suppresswarnings{} etc. Compilers should be able to ignore all compiler hints they don't support without affecting a progam which is sound. ( @assert() should never be used to test input, only to assert that the logic is correct ).
It needs grammar-support if you want to avoid making comments "magic". It also needs compiler support if you want to support advanced IDEs or features such as compile-should-fail-on-any-warning.
