It is, of course, his choice, but I'm suggesting that there is an alternative where all available resources are focused on the future, benefiting new projects at the expense of whatever remains of the legacy, going for strongest ultimate interest even at the possibility that it might not produce the strongest initial interest, and attempting to own the mindshare of "best system for new Python projects" by positioning itself exclusively as that, not positioning new Python project support a recent add-on to an old, legacy technology.
It's a matter of choosing market, positioning, and resource allocation, and I'm pointing out how, with a certain choice, the market perception that "mod_python is dead" doesn't have to be a problem and could even have advantages.
