It's usefull for the case where you have a meta-release (e.g. 
codec-engine 2.24.01) containing itself (e.g. codec-engine), but also 
matching parts like dsplink 1.63, lpm 1.14, etc. When building the 
meta-release you'll get all the parts you need with matching versions, 
but ideally you want the subpackages to keep their PV.

Another usecase would be a big external-toolchain tarball where you want 
to keep libgcc and libc versions when importing it into OE.
