We can make GNU build system tries autoreconf or autogen.sh first if we
encounter some build issues. But I don't think it's a good idea to
remove configure script in the snippet of origin. Because you can't
track all files that generated by Autotools. It is also burden for
packager to pick the build-time dependencies like libtool,
autoconf-archive, gnulib etc. if we force all autotools baseed packages
use autoreconf

For software developer, they prefer to bundle a generated configure
script because it will be a bootstrap problem sometimes.

A simple examples,the m4 macro GUILE_PKG defined in guile.m4 helps
autotools to check guile installation. If there's no generated configure
script. Software user should have guile.m4 to generate configure script.
A macro that detects guile installation requires a guile installation to
work. Catch 22 :)
