Can you explain a bit about how this helps folks with the textual dumps? It looks like this is more for folks trying to script the results, but those uses should be using the JSON dump output because that's actually structured output. The text node dumper is mostly used by folks who are in a debugger and want more information about what's being debugged, and for them these extra "details" bits are likely to be noise.
