One more thing: because the exact version of R that is used to build
binary packages is not necessarily the same between 2 versions of
Bioconductor, we would end up with binary packages that are different
(and possibly not interchangeable) but impossible to distinguish based
on their name if we were not bumping versions (e.g. both would be 
GWASdata_1.4.0.zip). Could make troubleshooting nightmarish.

Hope that makes sense,
