We deprecate it with a big warning that it's going away, because the waf
build is faster and generates smaller libraries and binaries.

How much faster?  About 12%.
How much smaller?  About 30%.

It also does much more checking, which has found real bugs.  Sure, it's
only marginally simpler to use (maybe because I'm not a python person?).
It is less lines of actual build scripts, even though it builds s4 as

Getting rid of the autoconf build will let us clean up include paths and
make s3's code cleaner.  I'd be delighted to do that work in a year or
