I completely disagree with this idea. We have spent almost two decades now
trying to enforce the idea that we provide a coherent set of packages that
are guaranteed at some level to interoperate correctly. And biocLite was
the way we provided that. People have always had the opportunity to use
install.packages directly, or just go to the website and download any
package version they might like. Changing that now, to (in some sense)
officially allow people to install whatever versions they like is IMO both
short sighted and against the whole idea of having a coherent set of
It's not really difficult (like, at all) to install whatever version of
package you might want, but making it easy for naive users to mix-n-match
doesn't make any sense to me at all.
