No, I think you are wrong.
First of all, I can see no benefit in pushing a package that cannot do
its basic function to Rawhide. Even in Rawhide, no one wants a kernel
that doesn't boot, even if in some circumstances they could go to the
trouble of downgrading their kernel. If we can test these situations
easily and reject these packages, we should just do it. (libguestfs
%check is a proof by example that such a thing is possible and easy in
Secondly, it does matter that in Rawhide you can at least get to the
login prompt, log in, and get a shell. AIUI this was the basic idea
behind the critical path packages. From the shell you have a hope of
fixing things. Your browser not working is a problem you might be
able to fix with a shell. Your kernel hanging under disk load or
hanging in init scripts (both actual problems with the current Rawhide
kernel) is a good deal more complex to fix.

libguestfs lets you edit virtual machines. Supports shell scripting,
bindings from many languages. http://et.redhat.com/~rjones/libguestfs/
