No, it won't as we have competing %{version}-%{release} strings among multiple
packages. E.g. perl source bundles an Encode module. And we know the module
is updated frequenly on CPAN. Thus we build perl-Encode-V1-R1 from perl.spec,
then we build perl-Encode-V1-R2 from CPAN perl-Encode.spec so that R2 >= R1, 
then we
rebuild perl.spec again with disabled perl-Encode subpackage.

With unpredictable releases we would have to fake version of the bundled
module so that it is always lower than a version of the standalone package.
Not impossible but, a nuissance.
