This just means that debuggers have to catch up. Anything that runs on a CPU is also debuggable, and if it's too much hassle, the debuggers need to improve. Debuggers are much more than just stepping through code and setting breakpoints, they are (or should be) "interactive program state explorers and visualizers". (IMHO no programming language should add features which make interactive debugging harder, it's never worth it in the long run)
