Description of change
Some tools are now relying on 9229 to be node.js "inspector" port (I see Chrome extensions, some online blog posts, etc.) Also, having same default port values for old and new protocols may lead to some confusion, e.g. when tools are trying to autodiscover debuggable Node instances.
