[Rd] methods cbind2 bind_activation disrupts cbind everywhere

The methods package ?cbind2 includes the instruction to use via methods:::bind_activation(TRUE). This changes the default definition of cbind globally, disrupting proper evaluation in packages not using cbind2. Is cbind2 a hold-over from a time when ... could not be used for dispatch? What is a safe way for a package to use cbind2?

This came up in the context of complex package dependencies in Bioconductor, as detailed in this thread (sorry for the html).
