Intstead of adding YAD (yet another directive ;) ), would it be possible to somehow leverage Listen itself, maybe with some sort of flag?
Yes, that would be quite possible. I was thinking about that way, but I have chosen YAD as a first approach. If you think adding flag to Listen is better way, I can rework my patch.

The difference between "Listen" and "FreeListen" is that "FreeListen" sets the IP_FREEBIND socket option on platforms where this is available. It is therefore possible to start the server even when particular IP address set in the "FreeListen" is not configured yet. This is needed for httpd startup with systemd when one wants to use particular IP address to bind. There is no way how to start httpd after the IP address has been configured in systemd and according to systemd developers, the applications should become more robust to handle network changes like that. The full reasoning is explained here [1]. The patch needs latest APR-trunk currently, but it could be rewritten to set IP_FREEBIND directly instead of using APR API (We use that way for REUSEADDR socket option). Do you think FreeListen is good name for this feature, or would you name/implement it differently?
