Correcting that last line for you:
... ld with no _direct_ benefit to 99.9% of users.

A major part of the _indirect_ benefit to all users of having a default
linker script is forcing the creation and maintenance of documentation
that matches what the algorithm actually _is_.

Nick's message "Commit: Fix test for .dynstr section" of 2011-06-10
was because of a bug I encountered while trying to figure out what
the PHDRS section should be.  I believe that the cause of the bug
was poor documentation of what the algorithm is.
