Wow, I had completely forgotten about this.
I see I even wrote a corresponding documentation patch.

Loss of memory.

Is there a bug open for this?  Anyway, I will look at it when I look
into the other issues with the new DWARF reader.

I looked and I can't find my patch to change how .debug_names is
constructed.  Hopefully that won't be too hard to rewrite.  However, I
did find a patch that I had forgotten about that changes .debug_names so
that it can write out a BFD, solving the string table problem (though I
still didn't write the reader side of this).
