An excellent example, I think.  See CR 4808196.

That certainly reduces the number of accurate parsers needed, but it
likely increases the difficulty of upgrade.  In order to upgrade, you
need an application that can run on the oldest system to be upgraded
(as well as the current one) and parse the oldest version of the
configuration file.

One of the attractions of plain old text files is that the upgrade
process can trust that basic text tools such as awk are present and
can run a script that we design in the future to manage that
transition.

If we're talking about compiled applications instead of scripts, we
need to be compiling those _new_ applications on the oldest systems we
support so that the binaries that perform the upgrade actions will run
on the systems we want to upgrade, and thus just forget about using
new OS features.  (Or, alternatively, we just abandon the concept of
LU.)

TANSTAAFL.
