i'm not sure this trade-off is worth the effort. sure, it'd be nice, but it'd be non-trivial to make sure backwards compat is maintained, and no one would really ever test it. we could do something like gettext where every release bundles all previous versions and then selects the "right" one on the fly. but for distros that patch things, that'll get messy too. and how many previous versions should we bundle ? some distros make it easy to install multiple versions in parallel. Gentoo for example has automake-X.Y so devs can pick the right one for their setup, with a common "automake" tool that detects the version used in the source tree and runs the corresponding version if available. maybe we could make that a more formal project ? we could also make it easier for distros to install multiple versions in parallel. the current info page logic doesn't make this easy.
