 // Node.js util APIs we're currently not supporting
-// TODO(soon): Revisit these

-// debug/debuglog -- The semantics of these depend on configuration through environment
-//                   variables to enable specific debug categories. We have no notion
-//                   of that in the runtime currently and it's not yet clear if we should.
-// deprecate -- Not clear how broadly this is used in the ecosystem outside of node.js
-// getSystemErrorMap/getSystemErrorName -- libuv specific. No use in workerd?
-// is{Type} variants -- these are deprecated in Node. Use util.types
-// toUSVString -- Not clear how broadly this is used in the ecosystem outside of node.js.
-//                also this is soon to be obsoleted by toWellFormed in the language.
-// transferableAbortSignal/transferableAbortController -- postMessage and worker threads
-//      are not implemented in workerd. No use case for these.
