Maybe in an ideal world, but here in the real world, not all patches get 
upstreamed immediately in the next release, and unless this is a large 
organized project like GCC which enforces very precise autotools versions, the 
next release will often have used different autotools versions (either because 
a different developer (often using a different distribution) generated the 
autotools files or because the maintainer upgraded his autotools, which happens 
often if they're using e.g. Debian unstable (also if they use Fedora, but in 
that case, you have at least some hope of hitting the same autotools versions 
they used)) and so a patch containing lots of bogus changes (i.e. differences 
completely unrelated to your actual modifications) will almost certainly fail 
to apply.

And this is a really complex solution with lots of manual work for the 
maintainer to do at each upstream release (your proposed Makefile.common 
snippets only automate small parts of it, which are just basic diff and patch 
invocations anyway), you didn't even list all of them (for example, the source 
tarball has to be extracted to rediff a patch).

So I don't get at all how you can think that this compares in simplicitly with:
BuildRequires: autoconf automake libtool
[and in the %prep section]
autoreconf
