Agreed. How (and whether) MCVersions are serialized is an implementation
detail of the repository implementation. Early on we expected more
diversity of repository implementations - Magma, Gemstone, peer images etc.
There was even a transactional store that got junked shortly before Avi
started showing people what we were working on. In practice we seem to have
settled on http and file repositories, so there does seem to be an
opportunity for optimization. However, even if we make that optimization,
extensions like TweakMC shouldn't rely on it to be able to function
