no, you're missing the point.  the .config file represents your
selection of kernel options, it's what you can hand to someone if they
want to reproduce your configuration.  autoconf.h, on the other hand,
is automatically generated from your .config file once you start the
build process.  it is in no way "obsolete", it's used by the build
process -- it's just not meant to be manipulated by users.

don't worry about autoconf.h, just leave it alone -- the build process
takes care of it.
