It makes sense, and actually I missed some logic w.r.t.
enabled/disabled being a list of sockaddrs (based on servers'
server_addr_rec, and not a global boolean as I first thought...). This
is later compared to incoming connections local addr.
Let me grok that... but at first glance it looks quite cumbersome, why
not the usual server merging and a simple "enabled" boolean?
If we only care about the config of the base server,
&remoteip_module)" could do it no?
For now it seems that all the vhost selection logic is duplicated, but
indeed it's not global (nor really per vhost, but yes this is thee
scope which comes closest).
