README files in etc directory?

Are the README files in the <topdir>/etc directory still useful?  It seems
that probably most of the information is out of date, and the documentation
of problems has probably shifted to either savannah for bug reports or the
wiki for workarounds.  I ask because README.MacOS (last updated 2/19/2011)
still refers to "automake (>= 1.11)".  This should now be 1.14, but if no
one is using these files then we should get rid of them entirely to reduce
the maintenance burden.
