This all falls out of the (very old version in SmartOS's case) Node.js
automatic generation of debugging symbols for itself, and tools like DTrace.

SmartOS uses a (very old) version of Node.js.  Its debugging support uses
objdump to turn internal state values into a header file for debugging tools
like DTrace and mdb_v8.  I'm stuck with a very old version because Node
apparently didn't value interface stability (and introduced so many breaking
changes it forced a version freeze upon SmartOS & friends), but that's a
history I'm not familiar with (having not been in SmartOS-land in its early
days).

illumos (the still-open successor of OpenSolaris) and its distributions have a
strong interface stability-and-documentation culture, which can sometimes be
annoying to folks, but has proven to be robust well after Oracle re-closed the
barn door.

Persistence until resolution is also a trait of illumos culture.  Thank you for
understanding. I think we're good now, and it looks like this is closed so it
looks like you think we're good now too.  Thank you!
