All OpenBSD developers work on -current and commonly on multiple platforms. Snapshots are rolled continuously for most platforms and made available to anyone who wants to run the latest code without having to build it themselves. The entire ports tree is compiled regularly on -current too. The compiled packages are then made available.
Last I knew, it was less about the effort, more about the license. And if you really need/want Apache 2, it's available in the ports tree and as a package. #> pkg_add apache-httpd
