Apache was removed from base in 2014, but nginx was added to base in 2011. Sysadmins had ~2 years to migrate from Apache to nginx (and if they didn't want to migrate, they could continue to use Apache from ports). For nginx, they only had 6 months to migrate (though again, they can still use nginx from ports). So no, they didn't have to migrate the http configuration twice a year, more like twice in 4 years, although, considering that OpenBSD only ever included into base 3 web servers, more like twice in 16 years.
