If it can get into the installers another way, it doesn't, really. It only needs to be in the source tree for 3.4+. Alternatively, we could be explicit that the "don't remove it" guideline only applies in 3.4+, where it will be needed by pyvenv. That way, people doing custom builds from source can easily bootstrap pip and we don't need to come up with an alternate solution for getting them into the installers.
