The main use case is to have a sandbox where you can deploy a
configuration of python packages to support an existing application
where you can't (reasonably) adjust all the buildroot versions of the
similar python packages to match.  My plan is to build the main OS
build using buildroot and then combine the existing virtualenv into
the rootfs for deployment.  There isn't a runtime need to any dynamic
changes to the env.
